Full Stack Developer
tl;dr: fullstack developer who loves building and shipping — React / Angular / Spring Boot, based in Rennes, France
I'm first and foremost a Full Stack developer, working with React, Angular and Spring Boot. I'm also a UI/UX designer: I did graphic design for a long time alongside my computer science studies, notably for clients.
I place a lot of importance on agentic AI and AI-driven automation, and I like keeping an eye on a project's security, networking, infrastructure and DevOps. My MIAGE* background also gave me a strong interest in finance and business management, and I'm proficient in the Agile Scrum methodology.
I adapt quickly to different contexts and enjoy owning a project end to end. Currently backup technical lead at Capgemini, I'm open to opportunities as a fullstack developer, at a company, startup or scale-up.
*MIAGE, in a sentence: a specialized Master's program combining Computer Science & Software Engineering with Business Management & Information Systems Architecture.

Agentos — AI Agent Orchestration · 2026
A tool that analyzes a repository to automatically identify the AI agents and skills a project needs.
July 2026
Side project around agentic AI, built with Next.js and Claude (.claude/ folder).
Agentos imports a repository path and automatically identifies the agents and skills a project needs, based on a clear hierarchy:
Super orchestrator → Orchestrators → Experts
Graph visualization of a project's agent hierarchy
Skills assigned based on each agent's position in the hierarchy
Every agent is humanized and personalized (name, own personality)
Suggestions to improve task allocation
Reduced token consumption
Marketplace (work in progress) of skills and agents that can express themselves, for example:
"Léo (git manager): I'll rebase on develop first, then commit & push the new feature!"
An orchestrator should always know who to delegate to, and an expert should always know what to do without getting it wrong.
