Summary
Hi! I’m Christopher Groß - Fullstack Developer and freelancer from Hamburg. I’ve been writing code since 2005, and working full-time as a freelancer since 2018. Remote, on an hourly basis, sometimes solo and sometimes supporting existing teams.
I started out in the gaming industry with complex payment and shop systems, followed by agencies and startups across all kinds of industries. One thing has always stayed the same: I don’t just want to get things working, I want to build them properly.
I’m a developer with 20 years of experience – and by now also an AI Orchestrator. I know both worlds, and I know how to connect them. AI makes me faster and more productive, but the craft behind it is still mine.
