Building open-source infrastructure for modern manufacturing. Boring is Awesome.
I write about manufacturing tech in plain language. Some of it ended up on Wikipedia and Hacker News (Kidnapped by Deutsche Bahn, AWS vs Hetzner, Node-RED).
In my free time, I read tech books like Designing Data-Intensive Applications and browse Hacker News. Games: mostly indie titles like Balatro and Vampire Survivors, with the occasional AAA exception like Baldur’s Gate 3. League of Legends remains a constant.
Things I Believe
I have strong opinions, loosely held.

Professional Journey
Since 2021: Co-Founder & CTO, UMH. We make open-source data plumbing for factories. Seed funding from Freigeist Capital in 2024, €5M in January 2026 led by KOMPAS VC. I also maintain gopcua, the native Go OPC-UA library. ISO 27001 certified.
McKinsey Singapore before finishing my bachelor’s. Got ripped apart, but now I speak management. Then I worked at McKinsey’s factory lab in Aachen, where I saw how broken factory software really is. After that I became a system integrator. 20+ industrial analytics projects. Installed, wired, debugged. Learned what actually survives the shop floor.
When I studied, I was Chair of the Local Board at bonding studenteninitiative. Taught me leadership by showing me what not to do.
Talks
I speak at conferences and meetups about manufacturing tech, cloud-native infrastructure, and industrial IoT.
