Hi there, I'm Dennis. I come with over 20 years of experience in the tech realm. My recent journey has been marked by the transformation of a 30-person startup into a well-funded unicorn with a team of over 1000. Every step of the way, I've been at the forefront, shaping and refining the tech department and its architecture. At the core of my work lies a strong emphasis on security, stability, and compliance. I have successfully led teams and contributed to the development of systems, architectures, and products that meet the highest standards in these and other critical areas. My leadership skills combined with a deep technical background and a strong set of personal values enable me to bridge the gap between technology and effective management, ensuring both innovation and operational excellence of cutting-edge products. Technology, for me, is not only a powerful tool for positive change, but also a certain way of looking at things. A mature, senior "Tech Mindset" is nowadays a magic wand to create sustainable, efficient solutions in an increasingly complex world. In addition to my work, I am a father, an avid explorer and a diligent student of the spiritual teachings of the Far East. I have a deep interest in the intersection of science and philosophy, in particular quantum physics, elementary particle physics, reality theories and philosophical idealism. In the last years, I have had the chance to learn a lot from great experts and leaders in the Startup and FinTech fields. If I can pass on some of these things, I’ll be happy to do so. Disclaimer: I offer mentoring sessions in my spare time. I would like to ask that you do not book sessions to sport a sales pitch for your product. Thank you.

I was very much looking forward to talking to Dennis, due to his wealth of experience, and his stellar career that led him to become the CTO of a well-known fintech company. Currently, I am part of the senior management at a large company, reporting to the CTO, and my goal is to become an executive myself one day. For my mentoring session with Dennis, I came with a number of concrete questions regarding executive leadership and business continuity, and we also went in-depth on career advancement. He asked a number of very pointed questions that illuminated some of the complexities behind the challenges I am currently facing. Overall, I found Dennis to be very insightful and also really easy to talk to. He is an extremely clear communicator. I took notes not only on what he told me but also on how he asks questions. This was a genuinely helpful session, and I benefited a lot from it.

The sessions was awesome - I did not just get a better understanding of what matters for me / us in our current hiring process but also felt understood. I always love to exchange with new people and especially enjoyed the session yesterday evening. There are still so much notes for me to order and summarize from yesterday.

First of all, thank you Dennis. I came with a concrete question to Dennis in mind and left with 2 very important but unexpected questions for myself. I believe this is exactly the way to mentor and help someone to tackle their impediments. Dennis is very professional, compassionate and knowledgeable manager that has a wide range of expertise which he is willing to share. I am looking forward to having another session in the future.

The session with Dennis was very insightful, and I'm already looking forward to our next conversation! He did not only help us with questions regarding our hiring- and product development-strategy but also shared insights on how investors will assess our current status from a technical point of view.

I was impressed by how Dennis gracefully has been juggling so many things during our session. My key points about our session: 1. Ask good questions > yes 2. Listen and encourage > yes 3. Guide the conversation > yes 4. Have a positive approach > yes 5. Generate personal responsibility and ownership > yes It was a great experience because I got my "home-works", a set of ideas that I can develop with my team.

I went into the session with a specific question in mind. Dennis quickly figured out that I needed to answer another question I was not aware of instead. I got great input and would like to schedule another session soon. Thank you, Dennis!

Dennis has provided insightful answers to my questions. He has provided experiences of his own to explain some topics and that contributed to the sincere vibe. The session was the first meeting to get to know each other, albeit it got already beyond that in a positive way. I am looking forward to have another session with Dennis in the future.
