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!

Sven is not only a developer who thinks along, but also very complex projects on request. He is fast, reliable and extremely accurate. Sven plans and implements even very complex projects with outstanding quality. There are very few developers of his caliber.
