Rotellini.
I build products end to end, piloting AI: I frame, I direct, I verify.
AI Product Engineer. React, Next.js, TypeScript and AI agents with Claude Code, from idea to production. Generalist developer turned AI-augmented builder: today I direct AI and audit the code it produces. Previously Decathlon, Damart, IÉSEG.

My AI products, built solo.
Built by piloting AI, from framing to production. I pilot Claude Code to develop; the products integrate whichever LLM fits the need, often Mistral for European compliance.

How I approach a project.
Based in Lille, I work remotely across France and the Benelux, or on site in Paris and Lille.
Building products by piloting AI
From idea to production, I frame the work, I direct the AI and I audit what it produces: moving fast without ever shipping what I don't control. Next.js, TypeScript, LLM integration when it adds value.
↳ ProductLLM integration
Wiring language models into real interfaces and workflows: agents, OCR, RAG.
↳ Applied AIModern React/Next.js front-end
Rebuilds, modules and integrations: fast, accessible and maintainable interfaces in React, Next.js, TypeScript.
↳ Front-endRecent clients: Decathlon, Damart, IÉSEG.
My workflow: I pilot the AI
I pilot Claude Code and equivalent AI tools across the whole development cycle, with judgment.
AI speeds up the code.
I don't ship what I don't control: context, validation and critical decisions stay in my hands.
