Back to original languageAbout Frédéric
Are you looking for a developer who can take your project from start to finish, from the back-end to the user interface, including mobile?
With 20 years of experience in Full Stack development, I support startups, SMEs, and large corporations in the design and implementation of robust, high-performance, and scalable web and mobile applications.
WHAT I BRING TO YOUR PROJECTS:
→ Complete architecture: API design (GraphQL, REST), database (PostgreSQL, MongoDB, SQL Server), and cloud deployment (AWS Amplify, Lambda, Scalingo).
→ Modern interfaces: React development for web and React Native / Expo for iOS & Android mobile, with a focus on performance and user experience.
→ Proven ecosystem: TypeScript, Node.js, Apollo Client/Server, C#/.NET — I choose the stack best suited to your context, not the one that's trendy.
→ Accelerated delivery: I integrate AI tools (Claude Code, agents, MCP) into my workflow to produce quality code faster.
SOME RECENT ACHIEVEMENTS:
• Logixper mobile application (React Native, GraphQL, AWS Lambda) — complete architecture and development, from the Hasura data schema to the Expo mobile app.
• United Managers multi-application platform (Meteor, React, React Native, MongoDB) — 5 years of development including real-time API, cross-platform mobile app, NodeBB forum, in-app purchases, and push notifications.
• E-commerce sites and extranets for travel companies (Voyageurs du Monde, TUI France, Go Voyages) — responsive redesign, SQL optimization, online interactive quotes.
• Lead Developer at SeLoger.com / BellesDemeures.com — development of the new LaCoteImmo.com website with integration of d3.js graphics and ElasticSearch.
I work fully remote or hybrid (Toulouse / Castres), available for short missions as well as long-term commitments.
