Summary

Since my school days I have been enthusiastic about electronics and computers. So it was only natural to combine the two and, for example, control a model railway or stereo system with a computer. I still love working close to the hardware, if necessary with a soldering iron and assembler. But I also enjoy developing desktop software whose "world" ends at the keyboard and monitor. Implementing new software is just as exciting to me as optimizing existing programs.
