About

I'm a generalist at heart. I'd rather understand a whole system than one slice of it, so I follow a problem wherever it goes and do whatever it takes to get something up and working.

I have a background in software development, but I'm also interested in design, businesses and branding. I like to think of myself as a creative problem solver, and I enjoy working on projects that have a positive impact on people's lives.

When I'm not at a keyboard you'll probably find me out with my friends, in the gym, doing music, enjoying a good meal or on a hike in the mountains.

Experience

My jorney in the tech industry and... life? It's been a wild ride, and I'm grateful for every twist and turn along the way.

Aug 2022 — now
I had the privilege of completing my "Applikationsentwickler EFZ" apprenticeship at LUKB. Alongside the fundamentals I picked up at vocational school and the continous learnings I did privately, those four years gave me the chance to grow both technically and on a human level.
