Back to original languageAbout Raphaël
🎯Full-stack developerfor 8+ years (front, back, mobile), from product launch in startups to project management for large accounts (**Total Energies**, **Saint-Gobain**).
🚀 I built and launched **Marmo**, a mobile app from A to Z (NestJS, PostgreSQL, Stripe payment, auth), and led teams of 4 to 5 developers on high-stakes front-end redesigns.
🤖 I useAIdaily to speed up boilerplate and exploration, but every line delivered is understood, reviewed, and owned; the tool accelerates, it doesn't replace judgment.
🧠 What I bring: the ability to choose the right technology rather than the trendy one, and to deliver a product that works in production, not just in demo.
✨ Main Stack:React.js/Next.js**, **NestJS**, **React Native
