CNC software at T&S Machines

Supply chain rerouting at HackZurich

Migros wanted to know which shipping routes to switch to when ports get disrupted. We built it in 36 hours and won the Migros challenge.

NASA Circadian Lighting

Spacecraft crews on long missions need lighting that tracks human circadian rhythms; plants need their own profiles. I built the controller.

§ 03 - NOW

Updated Apr 2026

Now

Working as a Digital Specialist at T&S Machines, mostly the Docker and deployment side of things. Looking for what's next: Docker, infra, or backend work, full-time. Remote preferred, but open to relocating for the right team.

Outside of work I've been trying to get less bad at guitar. Slow progress. Also building a slot machine game in PixiJS for fun, which is going about as well as you'd expect for a project with the words "slot machine" and "for fun" in the same sentence.
