Founder of VARAMI · AI Product Engineer
I build software for people who keep others moving.
Potsdam
For 15 years I have worked where domain experts and software teams have to understand each other: as product owner, technical project lead and product manager, from an international airport to physiotherapy practices.
Since 2010 I have been chairing a non-profit club for rehabilitation sport. There I saw how much time clubs and practices lose to paperwork, lists and billing. That is where VARAMI came from: a platform for courses, members and billing with health insurers, which I have been building entirely with the help of artificial intelligence since 2025.
