CTO and AI engineer based in Berlin with 22 years of experience building software, leading engineering teams, and shipping products in healthtech, AI, and developer tooling.
I spend most of my time writing code, building open source tools for AI-assisted development, and writing about what I learn along the way. My open source work focuses on practical skills, agents, and workflows for Claude Code, OpenAI Codex, and OpenClaw.
When I'm not coding, I write about AI engineering and agentic development on Medium (4,700+ followers) and in my newsletter.
claude-skills is a collection of 180+ production-ready skills and plugins for Claude Code, OpenAI Codex, and OpenClaw. It covers engineering, marketing, product management, compliance, C-level advisory, finance, and more.
The project has been featured on GitHub Trending and is used by thousands of developers to extend their AI coding agents with domain-specific knowledge and automation.
