Looking for a reliable e-commerce developer on Salesforce Commerce Cloud, capable of bringing real added value in architecture and performance? That's exactly what I do.
Certified Salesforce B2C Commerce Developer, 6 years on SFCC for major accounts (L'Oréal EMEA, Orchestra, Princess Tam Tam, Comptoir des Cotonniers). Full stack: SFRA, Business Manager, OCAPI, Page Designer, Hooks, Jobs, Services, Forms, ISML — back-end and front-end.
Concrete results:
— +30% display speed (customer area redesign, Madagence 2024)
— +15% front-end performance gain (Capgemini / L'Oréal 2022)
— United Retail API integration for omnichannel data aggregation (web + in-store)
— Klarna Pay Now activation + international multi-country selector
Full-stack React / Node.js / Next.js developer, I also work on high-stakes web and mobile projects, with artificial intelligence integrated at every stage of development.
In parallel, I develop web/mobile apps with AI as a daily tool. I use Claude Code for rapid prototyping and vibe coding (TDD, coverage > 80%):
— Dog Days: multiplayer 4X game (Next.js 14, TypeScript, MongoDB, Redis, Pixi.js — 17+ systems, 1,200+ tests, 28 API routes)
— Runova: gamified Couch-to-5K mobile app (React Native/Expo, Firebase, RevenueCat — 6 phases delivered in 14 days)
— Commis: AI pastry assistant (React Native/Expo, Gemini Flash, recipe scanning by photo, freemium)
My PhD in cellular biotherapy (UPMC Paris VI, 2018) taught me to structure complex problems, document rigorously, and see things through — reflexes applied daily in my missions.
Available for hybrid (Paris 3 days/week) or full remote missions, on a régie or forfait basis.
