I've fallen in love with programming when I was 11 and since then never stopped learning new programming languages, frameworks and libraries. I studied Computer Science and Media and finished with a Master's degree and a self-built IDE improving mobile development with Ionic. Over 7 years ago I decided to focus on mobile development using Android Native (Java/Kotlin), Ionic (JavaScript/TypeScript) and Unity3D. Since 2019 I'm fully committed using Google's awesome UI cross-platform toolkit "Flutter" to realize all of my mobile projects. I really enjoy writing high quality, readable, clean and maintainable code, using continuous integration/deployment and automated testing. Since I went through a lot of different roles during my career, I'm also very familiar with UX/UI design, creating prototypes to evaluate your project idea, software testing, support and managing a team using agile methods. I'm able to concept/design/program/test and maintain projects all by myself. What I could help you with: - decide for a technology when building your app - help you with Flutter/Dart problems or give you some tips how to structure your code, how to maintain it, keeping it clean and performant - discussing your app idea

I recently had a mentorship session with Verena and I must say it was an incredibly enriching experience. She provided me with a wealth of useful information and shared relevant links to help me improve my knowledge. Her guidance was extremely helpful as we had ample time to review my code, which allowed me to identify and work on areas that needed improvement. Verena was patient, encouraging, and very knowledgeable about Flutter. I truly appreciate her help and guidance, and I am looking forward to speak with her more. I highly recommend Verena as a mentor for anyone interested in learning Flutter.

Verena was amazing. As much as I have adored working with Flutter for the past year and a half, I've been unable to connect with virtually anyone else during my journey. First, just being able to share my work so far with Verena was incredible. She immediately contributed organizational ideas for my code (using Lint), and was not afraid to address the proverbial elephant in the room with every Flutter project (state management!!!). She provided actionable, workable, realistic steps for me to try to improve and was willing to give an example directly related to my code, which I am so very thankful for. She was willing to answer every question I had during the session. It was so good I am definitely going to cite some of what we discussed during my ongoing M.S. Thesis at Villanova. I cannot recommend Verena enough!

The Mom Test - How to talk to customers & learn if your business is a good idea when everyone is lying to you
Rob Fitzpatrick

Key Facts and Insights from The Mom Test: Everyone is lying to you: Not necessarily out of malice, but because they want to be supportive, encouraging, or polite. This is why it's not always wise to rely on friends and family for honest feedback about your business ideas. The Mom Test: A set of rules to help entrepreneurs get honest feedback. It involves asking about the person's life rather than their opinions about your idea. The test is passed if it gives valuable insight, regardless of whether the person knows about your idea or not. Focus on the problems: It's important to not just talk about your solution, but to also understand the problems that your potential customers are facing. This understanding is key to developing a product or service that truly meets their needs. Ask good questions: The quality of the feedback you get largely depends on the quality of the questions you ask. Avoid compliment-seeking, future hypothetical, and generic questions. Look for commitment or advancement: People's actions speak louder than words. Look for indications that they're willing to commit time, reputation, or money to your idea. Don't pitch your idea right away: Instead, have conversations about their life, challenges, and needs. This will help you to see if your idea fits into their life. Iterative learning: There's continuous learning involved in customer conversations. Each conversation should help you refine your idea and improve your understanding of your customers. Ask for concrete facts from the past: Instead of asking what they would do in the future, ask for specific instances in the past. This will give you a more accurate picture of their habits and needs. Don’t forget to follow-up: The conversation doesn't end once you've gathered information. Follow-up to clarify doubts, validate your assumptions, and maintain the relationship. Take notes and stay organized: Keep track of your conversations and learnings. This will help you see patterns, make connections, and track progress over time. In-depth Summary and Analysis "The Mom Test" by Rob Fitzpatrick provides a practical guide for entrepreneurs to validate their business ideas by talking to potential customers. The book's name comes from the idea that if you ask your mom whether your business is a good idea, she would most likely say yes to encourage you. But such kind of feedback, while well-intentioned, can lead to false positives and potentially result in business failure. Everyone is lying to you, not with the intention to deceive but to encourage or be polite. Friends and family, in particular, will often tell you what you want to hear, which makes their feedback untrustworthy. This is why Fitzpatrick introduces The Mom Test, a set of rules designed to get honest and useful feedback from anyone. The test entails asking about the person's life rather than their opinions about your idea. It's passed if it gives you good insights, regardless of whether they know about your idea or not. Understanding the problems that your potential customers are facing is as important as developing your solution. This perspective aligns with the principles of design thinking, a problem-solving approach that starts with understanding the user's needs. It's easy to fall in love with our ideas and ignore the problem we're trying to solve, but the real value lies in solving a problem that's significant to the customers. Asking good questions is key to getting valuable feedback. Fitzpatrick advises against asking for flattery, hypothetical questions about the future, and generic questions. Instead, we should ask about specifics in the person's life, their problems, and their needs. This concept is reminiscent of the Socratic method, a form of cooperative argumentative dialogue to stimulate critical thinking and to draw out ideas and underlying presumptions. Commitment and advancement are the real indicators of interest. People's actions are more reliable than their words. If they're willing to invest their time, reputation, or money in your idea, it's a good sign that they value it. This is in line with the Lean Startup methodology, which emphasizes the importance of validated learning and real customer feedback. Don’t pitch your idea right away, Fitzpatrick advises. Start by having conversations about their life, challenges, and needs. This is a form of customer discovery, a process used in Lean Startups to understand customer problems and needs. By exploring these areas first, you can see if your idea is a fit for their life. Iterative learning is integral to the process. Each conversation should help you refine your idea and improve your understanding of your customers. This aligns with the scientific method and the idea of forming a hypothesis, testing it, analyzing the results, and refining the hypothesis based on the findings. Asking for concrete facts from the past instead of future predictions can give you a more accurate picture of their habits and needs. This is because people are notoriously bad at predicting their own behavior, a concept known in psychology as the intention-behavior gap. Following up is crucial to validate your assumptions, clarify doubts, and maintain the relationship. This is similar to the concept of customer relationship management, which emphasizes the importance of maintaining a continuous relationship with customers. Finally, taking notes and staying organized is important to keep track of your conversations, see patterns, and track progress over time. This is akin to data management practices in research, which emphasize the importance of organizing and managing data for accuracy and reliability. In conclusion, "The Mom Test" provides practical, actionable advice for entrepreneurs to validate their business ideas. The book's principles align with established methodologies like Lean Startup, design thinking, and the scientific method. By applying these principles, entrepreneurs can avoid false positives, understand their customers better, and increase their chances of business success.

The Almanack of Naval Ravikant - A Guide to Wealth and Happiness
Eric Jorgenson

Key Insights from "The Almanack of Naval Ravikant" True wealth is the absence of a compulsive need to work - What matters more than having material wealth is having the freedom to choose how you spend your time. Embrace long-term thinking - Success comes from patiently putting in consistent efforts over a long period. Importance of specific knowledge - Specific knowledge is knowledge that you cannot be trained for. If society can train you, it can replace you. Leverage is a force multiplier - Capital, labor, and products with no marginal cost of replication (like software and media) are leverage that can amplify your output. Learn to sell and learn to build - If you can do both, you will be unstoppable. Embrace a growth mindset - Believe that you can improve with effort and learning. Skill acquisition is the best investment - The best investment you can make is in yourself, in acquiring new skills and knowledge. Happiness is a skill and a choice - Happiness is not something that happens to you, but something that you can cultivate. Meditation is a meta-skill that improves all other skills - By enhancing focus and reducing stress, meditation makes you better at everything else you do. Life is a single-player game - You are playing against yourself and your own standards, not other people. In-depth Summary and Analysis The book, distilled from Naval Ravikant's wisdom and insights, presents a refreshing and profound perspective on wealth and happiness. It emphasizes that true wealth is not just about accumulating money but about gaining the freedom to live on one’s own terms. This perspective aligns with the concept of 'Financial Independence, Retire Early' (FIRE), which I have been exploring in my research. Both Ravikant and the FIRE community espouse the idea that wealth should provide freedom, not tie you down to a lifestyle of conspicuous consumption. Ravikant's idea of embracing long-term thinking reflects the principle of compounding, a concept I often discuss in my lectures on economics and finance. It suggests that small, consistent efforts, when compounded over time, lead to significant results. This is applicable to wealth creation, skill acquisition, and even personal growth. The book's focus on the importance of specific knowledge and the power of leverage provides a valuable framework for understanding the dynamics of today's knowledge-driven, technology-fueled economy. As I often emphasize in my discussions on modern economics, in a world where automation and artificial intelligence are rapidly advancing, possessing unique, non-replicable skills and knowing how to leverage them is more essential than ever. One of the most potent ideas in the book is the notion that happiness is a choice and a skill. This aligns with the findings from positive psychology and the science of happiness, fields in which I have a keen interest. It rejects the common belief that happiness is a by-product of external circumstances or genetic predispositions. Instead, it argues that happiness can be cultivated through habits and practices like meditation, gratitude, and mindfulness. The book also asserts that life is a single-player game, a concept that resonates with the teachings of stoicism, a philosophy I frequently draw upon in my work. It argues that our main concern should not be how we compare with others, but how we measure up against our own standards and potential. This promotes a healthy sense of self-competition and personal growth. Overall, "The Almanack of Naval Ravikant" is a compelling guide to wealth and happiness in the 21st century. It combines timeless wisdom with modern insights to provide a roadmap for personal and financial success. Whether you are a student, an entrepreneur, or a lifelong learner, I believe there is much to learn and apply from this book.

Rich Dad, Poor Dad - What The Rich Teach Their Kids About Money
Robert T. Kiyosaki

Key Facts and Insights from 'Rich Dad, Poor Dad' Financial Literacy: The importance of understanding financial terms and concepts, such as assets, liabilities, income, and expenses. Assets vs. Liabilities: The importance of building assets, which bring income, and minimizing liabilities, which incur expenses. Work for Assets, not Money: The mindset shift from working for money to working to acquire assets. Financial Independence: The idea that financial independence, not a high income, is the key to wealth. The Power of Investing: The potential of investments to generate passive income and increase wealth. Understanding Taxes: The impact of taxes on income and how the rich use tax laws to their advantage. Entrepreneurial Mindset: The value of entrepreneurial skills and mindset in building wealth. Education and Self-Learning: The importance of continuous learning and acquiring financial education. Risk Management: The necessity of taking calculated risks to achieve financial success. Corporation vs. Employee Mindset: The difference between the mindset of an employee, who works for money, and a corporation, which makes money work for it. Importance of Mentors: The significance of having mentors and learning from other people's experiences and mistakes. Analysis and In-depth Summary 'Rich Dad, Poor Dad' by Robert T. Kiyosaki is a seminal work that offers a fresh perspective on personal finance and wealth creation. The book mainly contrasts the financial practices and beliefs of Kiyosaki's two 'dads'—his biological father (Poor Dad) and his friend's father (Rich Dad)—and how their differing views influenced his understanding of money and investing. The book illustrates the importance of financial literacy, emphasizing that understanding financial terms and concepts is crucial to wealth accumulation. This view aligns with existing research that underscores the link between financial literacy and successful financial planning. One of the critical concepts in the book is that of assets and liabilities. Kiyosaki defines assets as anything that puts money in your pocket, like investments and businesses, while liabilities take money out of your pocket, such as mortgages and car loans. He stresses the importance of accumulating assets and minimizing liabilities to build wealth—a fundamental principle of personal finance. Kiyosaki also encourages readers to work for assets, not money. He argues that the traditional mindset of trading time for money limits wealth creation. Instead, he advocates for acquiring assets that generate income over time—a concept reminiscent of the 'money as a tool' philosophy. Financial independence, according to Kiyosaki, is more crucial than high income. He explains that it's not about how much money you earn but how much you keep and how many generations you can keep it. This idea aligns with the principle of 'financial freedom,' where your income from assets can support your lifestyle without the need for active work. The power of investing is another key theme in the book. Kiyosaki emphasizes that investments—in real estate, stocks, or businesses—can generate passive income and enhance wealth. He also discusses the concept of 'return on investment,' which is a significant consideration in investment decisions. Kiyosaki also explores the impact of taxes on income and how wealthy people strategically use tax laws to their advantage. He notes that understanding tax laws and structures can help individuals maximize their wealth—a concept often overlooked in traditional education. In 'Rich Dad, Poor Dad,' Kiyosaki also advocates for an entrepreneurial mindset. He believes that entrepreneurial skills such as problem-solving, leadership, and risk-taking are vital in wealth creation. This perspective ties in with the 'entrepreneurial revolution' theory, which states that entrepreneurship is a key driver of economic growth. The book also emphasizes education and self-learning. Kiyosaki criticizes the traditional education system for its lack of financial education and encourages readers to seek knowledge independently—a principle consistent with 'lifelong learning' philosophy. Risk management is another prominent theme in the book. Kiyosaki advises taking calculated risks and learning from failures—an idea that dovetails with the 'risk-reward tradeoff' concept in investing. The book also contrasts the mindset of an employee and a corporation. Kiyosaki argues that the wealthy make money work for them, unlike employees who work for money. This idea underlines the 'money as a servant, not a master' philosophy. Finally, Kiyosaki underscores the importance of mentors in financial success. He credits his 'Rich Dad' for his financial acumen, suggesting that learning from others' experiences and mistakes can fast-track one's financial success. In conclusion, 'Rich Dad, Poor Dad' provides a comprehensive guide to personal finance and wealth creation. It challenges conventional wisdom on money, encourages financial literacy, and promotes an entrepreneurial mindset—all essential elements in the journey towards financial freedom.

Start With Why - How Great Leaders Inspire Everyone To Take Action
Simon Sinek

Key Facts and Insights from "Start With Why - How Great Leaders Inspire Everyone To Take Action" The Golden Circle: At the core of Sinek's theory is the three-layered model known as the Golden Circle. It encompasses 'Why', 'How', and 'What' as the fundamental aspects of any organization or individual's purpose. Importance of 'Why': Sinek emphasizes that most successful organizations and leaders start by defining 'Why' they do what they do, not just 'What' they do or 'How' they do it. Leadership and Inspiration: The book underscores that successful leaders inspire action in their followers by articulating a clear 'Why' and aligning it with the beliefs of their followers. Manipulation vs Inspiration: Sinek distinguishes between manipulation (using external factors to drive behavior, like price, fear, etc.) and inspiration (motivating through a deep-rooted sense of belief or purpose). Clarity of Purpose: Clarity of 'Why' is crucial for any organization or leader to succeed and inspire others. This clarity is often missing in companies that struggle. 'Why' and Trust: When organizations and leaders communicate their 'Why', it helps build trust and loyalty among their employees or followers. The Role of Innovation: Sinek posits that innovation is born from a strong 'Why'. It's not just about doing things better, but doing them for a better reason. 'Why' and Culture: A clear 'Why' helps create a strong culture where employees feel they are contributing to something bigger than themselves. Companies as a Reflection of Leaders: Companies often reflect the persona of their leaders, especially their 'Why'. This is why it's crucial for leaders to have a clear sense of their own 'Why'. Consistency of 'Why': The 'Why' should remain consistent even as the 'What' and 'How' might evolve over time. Detailed Analysis and Summary of "Start With Why - How Great Leaders Inspire Everyone To Take Action" Simon Sinek's "Start With Why" presents a transformative perspective on leadership and organizational success. At the heart of his argument is the Golden Circle, a model composed of three fundamental elements: Why, How, and What. These elements, Sinek asserts, form the basis of any individual's or organization's purpose. However, he emphasizes on the importance of starting with 'Why'. Why is the purpose, cause or belief that drives every one of us. Many organizations can clearly articulate 'What' they do and 'How' they do it, but the 'Why' often remains elusive. Sinek argues that this is where many organizations falter. Drawing parallels with biological concepts, he positions 'Why' as the limbic brain (responsible for feelings, such as trust and loyalty) and 'What' and 'How' as the neocortex (responsible for rational thought and language). When it comes to leadership, the book posits that great leaders are those who inspire action by articulating a clear 'Why'. Leaders like Martin Luther King Jr. and companies like Apple are successful not because of what they do, but because of why they do it. They start with 'Why' and then move outwards to 'How' and 'What'. This approach resonates with people's beliefs, thereby inspiring them to act. Sinek distinguishes between manipulation and inspiration. While manipulation involves driving behavior through external factors such as price, promotions, fear, or peer pressure, inspiration comes from a deep-rooted sense of belief or purpose. He asserts that manipulation can lead to transactions, but only inspiration can foster loyalty. The book also stresses the importance of a clear 'Why' in building trust and loyalty. When organizations and leaders communicate their 'Why', it resonates with their employees or followers on an emotional level, leading to increased trust and loyalty. Innovation, according to Sinek, is a byproduct of a strong 'Why'. It is not merely about doing things better, but about doing them for a better reason. This perspective aligns with the theory of innovation diffusion by Everett Rogers, who highlighted that people adopt new ideas or products not because of their advantages, but because they align with their beliefs. Sinek also discusses the role of 'Why' in creating a strong culture. A clear 'Why' provides employees with a sense of purpose, making them feel they are part of something bigger than themselves. This is reflected in the principle of 'Cultural Fit', which suggests that employees perform better when their personal values align with the organization's values. The book further suggests that companies often mirror the 'Why' of their leaders. This is why it is crucial for leaders to have a clear sense of their own 'Why'. Finally, Sinek emphasizes that while 'What' and 'How' may change over time, the 'Why' should remain consistent. This consistency of 'Why' is essential for maintaining the trust and loyalty of employees and customers. In conclusion, "Start With Why" offers profound insights into how great leaders inspire action. It makes a compelling case for starting with 'Why', thereby transforming the way we understand leadership and organizational success. Sinek's philosophies, when applied, can indeed lead to more inspired employees, loyal customers, and successful organizations.

Effective leadership is about creating a culture of continuous development and learning. Leaders should focus on creating value for the company and its stakeholders. The importance of work-life balance for a leader's productivity and health. Leadership is a journey of personal and professional development. Detailed Summary and Analysis Merath's book "Dein Wille geschehe - Führung für Unternehmer. Der Weg zu Selbstbestimmung und Freiheit" emphasizes the importance of leadership in the realm of entrepreneurship. The book defines leadership as a path to self-determination and freedom, where a leader sets the vision and direction for a company. This notion aligns with the transformational leadership theory, which posits that leaders inspire and motivate their followers to exceed expectations, rather than simply commanding and controlling them. The book underscores the significance of emotional intelligence and self-awareness in successful leadership. These concepts are deeply rooted in the theory of emotional intelligence by Daniel Goleman, which suggests that leaders who understand their own emotions, and can empathize with the emotions of their team members, are more effective in their roles. Merath identifies these characteristics as crucial for building trust and fostering a healthy and productive team environment. In addition, the book highlights that good leaders are not afraid to take risks and learn from failures. This perspective resonates with the concept of failure as an opportunity for learning in leadership literature. Moreover, it is reminiscent of the idea of a 'learning organization', as proposed by Peter Senge, where mistakes are viewed as opportunities for learning and improving. A significant part of leadership, according to Merath, involves empowering your team to make decisions and take responsibility. This idea is a cornerstone of participative leadership. By promoting a culture of empowerment and responsibility, leaders not only improve the decision-making process but also increase the motivation and commitment of the team members. Merath also emphasizes the need for leaders to focus on creating value for the company and its stakeholders. This idea is anchored in the stakeholder theory, which proposes that businesses have a responsibility to all their stakeholders, not just shareholders. By creating value for all stakeholders, leaders can ensure the long-term success and sustainability of their organizations. The author also addresses the importance of work-life balance for a leader's productivity and health. This is a crucial reminder in today's fast-paced and high-stress business environment, where burnout is a common concern.

Finally, Merath portrays leadership as a journey of personal and professional development. He encourages leaders to invest in continuous learning and growth, not just for the benefit of their organization, but for their personal development as well. This perspective aligns with the concept of lifelong learning, which is increasingly recognized as essential in the ever-evolving business landscape. In conclusion, "Dein Wille geschehe - Führung für Unternehmer. Der Weg zu Selbstbestimmation und Freiheit" offers a comprehensive exploration of leadership in entrepreneurship, emphasizing self-determination, freedom, emotional intelligence, risk-taking, empowerment, value creation, work-life balance, and continuous learning. It is a valuable resource for both aspiring and established leaders in the business world.

Clean Code - A Handbook of Agile Software Craftsmanship
Robert C. Martin

Key Insights from Clean Code - A Handbook of Agile Software Craftsmanship The importance of writing clean code and its impact on software maintenance and scalability. The principles of SOLID design: Single Responsibility, Open-Closed, Liskov Substitution, Interface Segregation, and Dependency Inversion. How to correctly use comments in code and when to avoid them. The significance of meaningful names for variables, functions, classes, and modules. The concept of functions: how they should be small, do one thing, and do it well. The art of error handling and the importance of throwing meaningful exceptions. The principles of Test Driven Development (TDD) and the importance of writing tests first. The importance of keeping the codebase clean through continuous refactoring. The idea of code smells and how to identify them. How to manage system dependencies to ensure loose coupling. Analysis and Summary of the Book "Clean Code - A Handbook of Agile Software Craftsmanship" is a comprehensive guide that provides a deep dive into the principles and practices of writing clean, readable, and maintainable code. The book is grounded in the author's deep experience and understanding of software development and its challenges. The book opens with an emphasis on the importance of writing clean code. It asserts that code quality is a fundamental aspect of software development that directly impacts the maintenance, scalability, and overall health of software projects. It argues that code is read far more often than it is written, making readability a key quality attribute. The book introduces the SOLID design principles, a set of guidelines for object-oriented design and architecture. These principles aid in the development of software that is easy to manage and maintain, with a focus on avoiding code smells, reducing complexity, and improving readability. Comments are a double-edged sword. While they can provide important context and explanation, the book argues that they are often used as a crutch to justify complex or confusing code. Comments should not replace clear and concise code. Naming conventions are another crucial aspect of clean code. The book explains the importance of choosing meaningful and descriptive names for variables, functions, classes, and modules. Names should convey intent and make the code self-documenting. The book also provides detailed guidance on how to write functions. Functions should be small, do one thing, and do it well. This aligns with the Single Responsibility Principle, one of the SOLID principles. Error handling is another key topic. The book stresses the importance of throwing meaningful exceptions and managing errors in a consistent and predictable manner. It also covers Test Driven Development (TDD), a software development process that promotes writing tests before writing the actual code. TDD helps in ensuring that the code is working as expected and leads to modular, flexible, and bug-free code. The book emphasizes the need for continuous refactoring to keep the codebase clean. Refactoring is not just about rewriting code; it’s about improving the design of existing code while preserving its functionality. Code smells are certain structures in the code that suggest the possibility of a deeper problem. They are indicators of poor design and coding practices that need to be refactored. The book concludes with a discussion on how to manage system dependencies to ensure loose coupling, which makes systems more manageable and less prone to bugs. In summary, "Clean Code - A Handbook of Agile Software Craftsmanship" is a must-read for any serious software developer or engineer. It goes beyond teaching specific techniques or practices, instead instilling a mindset and philosophy towards writing code that is clean, understandable, and maintainable. To master the art of writing clean code, one must not only understand these principles but also incorporate them into their daily coding practice.
