About me

AI-powered.
Human-driven.
Coffee-fueled.

Moin! I'm Christopher Groß - fullstack developer and freelancer from Hamburg. I've been writing code since 2005, full-time as a freelancer since 2018. Remote, on an hourly basis, sometimes solo and sometimes as reinforcement in existing teams.

I started in the gaming industry with complex payment and shop systems, followed by agencies and startups across all sectors. What has always accompanied me: the ambition not just to get things running, but to build them properly.

I'm a developer with 20 years of experience – and 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 remains mine.
