Over the years I developed a passion for multiple outdoor sports, and I took care to find matching sports for summer and winter.

But when moving to the Black Forrest, a hill region in south of Germany, more opportunities came along and the winters are not so nice for biking. So today it splits as follows.
After many years in the field of computer vision, I switched focus to cybersecurity, more or less by accident. Inside the same company.
In 2018 my job role suddenly changed from computer vision and image processing to managing development of data loggers. The scope of the project I joined was to develop a small temperature logger working offline most of the time and sending collected data via BlueTooth on button press. The device was 80 % finished and some one asked me to put “some security into it”. One brilliant engineer from a different team already had already proposed a concept with asymmetric encryption, private / public keys per device, certificates and an internal certificate authority, but he could not sell it to the development team or the management, so my role was more like understand both worlds, translate between tech and management and finally approve the concept. The implementation on the microcontroller was difficult due to restrictions in RAM and storage. But with the right libraries it finally worked out.
In June 2024 I finished courses and exams at mITSM in Munich and got the title ICO ISMS Security Officer according to ISO/IEC 27001:2022
