Hi, I’m Dennis.

I’m a father of two (*2006 && *2014), Buddhist, horseman, engineer by trait and an incurable optimist. I love music, talks, animes, series and multiple areas of tech if well-crafted. In the evenings, I sometimes find myself searching for planets through my telescope after having watched way too many videos on astrophysics, nuclear fusion or similar topics of which I understand only half of. Professionally, I am CTO at Solarisbank AG, Europe's leading Banking-as-a-Service platform. In this role, I’m responsible for the entire tech organization in all its aspects, making sure that we're building secure, stable and compliant products in a modern and efficient manner.

I have worked for more than 15 years as a software developer in agile companies with an increasing focus on systems development and automation. In 2014, I became a Certified Information Systems Security Professional (CISSP) of ISC². At Solarisbank, I moved to the management track, where I learned about the challenges on the executive level and how to build, steer and guide a team of 100+ people.

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.

  • People Development
  • Team Leadership
  • Organizational Development

He is a great mentor, he gave me a lot of helpful advice and answered every question I had.

I enjoyed this meeting with him because it was so informative and our conversation flowed very nicely. I learned a lot from him and hopefully, we are going to have another session in the near future.

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.

Danke für deine Zeit Dennis. Du konntest genau dort ansetzten, wo bei uns der Schuh drückt und direkte Lösungsansätze liefern. Hat mir wirklich Spaß mit dir gemacht.

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!

I enjoyed the discussion with Dennis. He was open to share stories and his knowledge. I did profit a lot from his experience - on a professional and a personal level. Thank you!

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.
