I have worked with Sven for over seven years, and I have to say that he stands out among the Java developers that are around today. Sven's superb attention to detail and vast technical knowledge always provided top-quality, thoughtful, and professional outcomes in any work.
With Sven's excellent mentoring and guidance ability, I gained high impact skills in solving complex problems and reached a new level as a developer. I highly recommend him to anyone who is looking for an efficient, talented, and skilled programmer!
Working with Sven really leveled up my Java and development skills! He provided invaluable guidance in all aspects of development, including concurrency, performance, reliability, and DevOps. Sven's focus on clean architecture meant our applications were simple to maintain and extend. He's always on the cutting edge of Java developments and is a pleasure to work with.
I had the pleasure of working with Sven for more than a year. Working with Sven means each day you learn a little more. A manager whose ability to handle multiple projects was unlikely any I had seen before and made a dramatic increase in the productivity level of our company.
Whenever I have questions or concerns, Sven responds right away and even follows up later in the week or month to make sure my issues have been resolved. His patience and willingness to help me motivated me to do the best job I can.
"Genuine expertise" is the phrase that comes to my mind when I think about Sven.
On a professional level, Sven and I are connected by more than 20 years, several company foundations, and the implementation of some very innovative ideas in the internet sector. Sven not only had the hat of the CTO but also of the software architect and lead developer. Also, the management of larger teams has been part of his tasks.
If you want to summarize Sven's performance and get to the point, I can only think of a quote from a very well-known business angel who once said: "Sven's software is not software. It is a piece of art".
