Jakob Pütz
Full-stack developer Aachen, Germany
I build and ship products people actually use. I started PFControl, a flight-strip platform for virtual air traffic controllers, at 15. Today it has 12,000+ registered users and around 500 daily actives.
Right now I'm building Weavay, an email client that threads mail into real conversations, and Petal, a memory-first AI workspace. I work across the stack with TypeScript, React, Postgres and Cloudflare. I'm 17, self-taught, and into aviation, space and photography when I'm not coding.
