About

Eight years running chemical tests at a cement lab in Lichtenburg. Routine, precise, underpaid. I was good at it. I was also bored out of my mind.

In 2022 I left and never looked back. Taught myself Python. Started entering hackathons for fun. Won some. Lost more. Built things that worked and things that didn't. Found AI — or maybe AI found me.

Now I build multi-agent systems, deploy real infrastructure, and ship code that runs 24/7. I'm not a "prompt engineer" — I write the pipelines, the APIs, the deployment scripts. The whole stack, from LangChain chains to systemd services.

When I'm not building AI, I'm DJing. Been at it since 2012. Co-founded Papzin & Crew — a platform for Mega-Mixers, not algorithm-curated playlists. Real mixes by real people. That same energy goes into everything I build: it has to be real, it has to work, and it has to move people.

Music

DJing since 2012. Co-founded Papzin & Crew in 2016 because Spotify playlists are boring and Mega-Mixers deserve a platform. Cruize Friday mixes, custom requests, 24/7 streaming — real music by real people.

Now I'm also experimenting with AI-generated music through Suno. Because why not? If the AI can make something that moves people, I'm in.
