Hey, I'm Carl!
I'm a proud dad and engineer building syntwin.ai.
I spend a lot of time thinking about product and design. How software feels matters to me. I'm a local-first enthusiast and PWA fanboy.
When not coding, I'm with my family, cooking or doing some kind of sports. I also organize the Munich TypeScript Meetup.
