Summary

I am a skilled system software developer, with excellent analytical abilities, solid education background, and strong dedication to reach my aims by working hard and creatively.

Being active in software development on various systems since the eighties, since 1990 I focus on UNIX with extensive experience as both systems programmer, user and administrator, including many classic internet services. I like working on design and architecture, and always keep operability in mind. Beside technical tools, at work I use methods of team management and quality management; encourage by visions and gain authority by competence.

I work well by myself and in a small team. I lead efficient meetings, preferring the structured and productive ways of communication known from many development mailing lists on the internet. I dislike travelling and prefer a video conference instead.
