We're Not Developers. We Built a 116K LoC Production System Anyway.

Most AI coding talks follow the same script: developers using AI to work faster. Refactoring legacy apps. Scaffolding CRUD services. Impressive — but expected.

This is a different story.

Daniel built the AFC Group from 3 employees in 2001 to a 350-person corporation, acquired nobleglass — today Germany's leading automotive glass business — in 2019, and drove its transformation into a mobile service operation as COO from 2023 to the end of 2024. His background is chemical engineering, management consulting, and an MBA — not software. Felix is a Head of Product who spent a decade in aviation IT and led operations tools at Volocopter — a technical mind, but one who left full-time development behind years ago. Neither works as a software engineer. Both built this part-time — weekends, holidays, evenings.

Together, with Claude Code and Pi, they built far more than a route planner. 116,000 lines of code. 2,100+ commits. 85 technicians, 40 depots, 150–200 jobs per day across Germany. In full production since January 2026. Continuously shipping. Not a prototype — the system that runs the operation.

The bottleneck in AI coding was never the code. It was always the domain knowledge. AI can generate any pattern you ask for. But only you know that morning time windows in Munich mean something different than in Hamburg. Only you know which constraint the dispatcher will override and which is sacred. That knowledge — 25 years of it — turns AI output from plausible garbage into a production system.
