I spent 16 years building software systems and production platforms, including 13 years at Mercedes-Benz. More recently I have been exploring what happens when coding agents make implementation dramatically faster, and what engineering organizations need to change when code is no longer the main constraint.

Selected Work

taurhaus / Mesh

Persistent multi-agent engineering teams

A cross-platform developer application for supervising Claude Code, Codex and Gemini across multiple projects and persistent agent teams. The project explored durable agent roles, cross-agent coordination, context recovery, worker health, and what happens when human attention becomes the limiting resource.

ZigQueen

AI-native chess engine with independently verified superhuman playing strength

A UCI chess engine built primarily through coding agents, with human ownership of architecture, experimentation, evaluation and release decisions. Its ~3570 Elo rating on the CCRL Blitz list is an external measurement of the result, not a subjective demo claim.

I Was the Bottleneck

Essay

What more than a decade of enterprise platform delivery and eight weeks of running AI agent teams at home taught me about where software organizations break next.

About

I am a computer scientist and engineering leader based in Germany. Before leaving Mercedes-Benz in 2026, I spent thirteen years building and leading cloud, backend and API platforms across Mercedes-Benz Vans and Mercedes-Benz Digital.

My current focus is AI-native software engineering: what coding agents can implement, and how faster implementation changes the way engineering organizations lead, decide and evaluate. More →
