About François

Je conçois, reprends et fiabilise des applications web, des produits SaaS et des fonctionnalités basées sur l’IA.

Développeur fullstack depuis plus de 10 ans, j’interviens principalement sur des projets TypeScript avec React, Node.js et l’écosystème Cloudflare. J’ai travaillé en startup, en fintech réglementée et en grand groupe, notamment chez Tokeny Solutions et BNP Paribas, avant de développer mes propres produits de bout en bout.

Je peux intervenir pour :

développer une application web ou un SaaS ;
reprendre et stabiliser un MVP ou une codebase existante ;
intégrer un LLM ou une fonctionnalité IA dans un produit ;
construire des APIs et connecter des services tiers ;
mettre en place des traitements asynchrones avec Cloudflare Workers et Queues ;
améliorer l’architecture, les performances et la maintenabilité ;
documenter le système et faciliter sa reprise par une équipe.

Stack principale : TypeScript, React, Node.js, Hono, Cloudflare Workers, D1, Queues, R2, REST, GraphQL, PostgreSQL et Stripe.

J’ai notamment développé Resonance, une application d’écriture assistée par IA utilisant React et l’infrastructure Cloudflare, ainsi que plusieurs produits SaaS couvrant le frontend, le backend, les paiements, le déploiement et la maintenance.

Mon approche est pragmatique : comprendre le besoin réel, éviter la complexité inutile et construire une solution claire, fiable et maintenable.

Basé à Rennes, je travaille à distance avec des équipes françaises et internationales. Français natif, anglais bilingue.
