Summary
- Profile
As a computer science graduate, I've been working for over a decade as a freelancer in automation and machine control. After studying core computer science in Dortmund with a focus on embedded systems, I first gained experience in my family business before going freelance.
My expertise is in developing robust applications for industrial and embedded hardware. I work with established technologies like C/C++ as well as modern languages like Rust and Go. From programming industrial communication protocols to building user interfaces, I cover the full range.
I've worked on interesting projects in the events sector, where my axis controls are used in renowned venues like the Semperoper Dresden and the Tiroler Festspielhaus. I also had the chance to contribute to the popular Thermomix devices at Vorwerk. In addition, I'm active in the open-source community.
Originally from the Ruhr area, I now live with my family in Cologne. In my free time, I enjoy sports - I'm training for various half marathons, ride road bikes, and go swimming.
