About Alexandre
Développeur fullstack senior (TypeScript, Next.js, React, React Native, Node.js), j’aide les équipes produit à livrer plus vite en structurant l’usage de l’IA autour de leurs projets web & mobile.
Plutôt que d’utiliser l’IA comme un gadget, je conçois des plans détaillés et des “skills” / agents IA adaptés à votre contexte : découpe fine des tâches, contraintes, validations, de sorte que l’implémentation soit en grande partie réalisée par l’IA, tout en gardant un contrôle humain fort sur l’architecture, la qualité et la sécurité.
J’utilise quotidiennement Claude et Cursor pour accélérer le delivery, automatiser tests, documentation et refactorings, et rendre vos codebases plus faciles à faire évoluer.
Avec 8 ans d’expérience et un rôle régulier de lead, mon objectif est de construire des systèmes où les devs se concentrent sur les décisions importantes, pendant que l’IA s’occupe du reste.
