I was interested in software since the late 1980s and started programming in 1991. I am a professional software developer with a degree in computer since since 2004. Since the late 1990s I'm mostly focusing on the web platform.
The following pages list software I either coded myself or contributed to. Some more software I made can be found on the website of my demoscene group TAP. Source codes are usually included in the downloads. I'm usually licensing my own software under the terms of CC-BY-SA, if not stated otherwise.
