Summary
- Profile Description
As a computer science graduate, I have been working as a freelancer in the field of automation and machine control for over a decade. After studying core computer science in Dortmund with a focus on embedded systems, I first gained experience in the 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 such as Rust and Golang. From programming industrial communication protocols to developing user interfaces, I cover the entire spectrum.
I have worked on interesting projects in the events sector, where my axis controls are used in renowned venues like the Semperoper Dresden and the Tyrolean Festival Theatre. I also had the opportunity to contribute to the popular Thermomix devices at Vorwerk. In addition, I am active in the open source community.
Originally from the Ruhr area, I now live in Cologne with my family. In my free time, I enjoy sports - I train for various half marathons, go road cycling and go swimming.
