About

I'm a fullstack developer and researcher based in Bordeaux. I fell into computer science young and never left, drawn by the idea that code isn't just tooling, it's infrastructure for society. That curiosity led me to distributed systems, cryptography, and eventually to the question I keep coming back to: how do we establish trust without a central authority?

The more I look at the web's architecture, the clearer the problem becomes. Every system of trust we've built still relies on someone at the center vouching for everyone else: certificate authorities, social login, identity providers. It works, until it doesn't. I'm interested in what comes after.

Today I build production SSI infrastructure at Verana, DIDComm messaging, verifiable credentials, trust registries. I also created Credat, an open-source library that brings the same trust model to AI agents, giving autonomous systems verifiable identities and scoped delegation. As agents become more capable and autonomous, the question of how services verify them, and who authorized them to act, becomes urgent.

I recently joined the Trust over IP Foundation to deepen the research side of this work. I'm 19, investing everything I have in this space, convinced that decentralized identity is one of the foundational problems of the next era. For humans, and for AI agents.

Before tech, I spent seven years training as a high-level parkour athlete, competing and teaching across France. In 2025, I co-founded PKBA, now the largest parkour club in Nouvelle-Aquitaine. Discipline, pattern recognition, and learning from failure fast, sports and systems thinking have more in common than they appear.
