Summary

Experienced embedded software developer (primarily C) with excellent hardware knowledge.

Many years of experience in electric motor control. Since my early work in the field of smart cards with their special requirements for security and quality, I have developed a strong sense for software architecture, design, and code quality. I enjoy applying these skills to solve even complex software engineering tasks and problems.
