Summary

Hi and thanks for visiting my profile page!

Starting self taught as and OSS developer creating the leading Java FTP implementation at http://j-ftp.sourceforge.net I grow to Senior Software Architect during my professional career.

My strength lies in getting things done quickly and with exactly as much effort as the feature desires, without compromising too much on test- and maintainability. In addition to that I have no problem in working with legacy code.
Where others see technical debt I might find a valuable asset providing business value, and I consider it very important that positive attitude prevails in a team even though some painful transitions might be necessary to enable further growth/scaling.

Software is never perfect, but with the right mindset even most business problems are not too hard to solve in a reasonable timeframe.

2016

Java

In the early 2000s I decided that the Java'S FTP implementation was not good enough and there were no adequate 3rd party clients. So I started implementing the RFC, and over time one of the leading clients evolved. It received lots of downloads, patches from other people and even some commercial usage due to GPL dual licensing. Altough the project has not received updates since 2016 I don't consider it abondened, just mature and stable!
