About Jean

How much time does your team waste correcting what AI generates?

Agentic engineering works, but not without structure. Claude Code is the most powerful tool on the market, but the tool matters as much as the codebase and the method. It took me months to structure a workflow that works in production at Odisei Play. CLAUDE.md, repo conventions, adapted review. The dev+design team uses it daily.

On assignment: I audit your existing setup, restructure the repo to make Claude Code effective, and transfer the method to your team. You leave autonomous with a blueprint that the agent uses directly.

Freelance Lead React Native Engineer for two years on Odisei Play (Expo, TypeScript, animations, real-time audio, BLE, react-native-skia). I understand the constraints of a real production app.
