Summary

Ever since school I've been passionate about electronics and computers. So it was only logical to combine them and, for example, control a model railway or stereo system with a computer. This was followed by a computer science degree, a correspondingly hardware-related diploma thesis, and starting my career in research and development. I still enjoy working close to the hardware, even with a soldering iron and assembler if needed. But I also like developing desktop software whose "world" ends at the keyboard and monitor. I find implementing new software just as exciting as optimizing existing programs.
