About

Engineer first, founder by conviction.

I'm an AI engineer turned CTO. Trained at ESILV and CentraleSupélec (MSc in AI), I shipped chatbots, voicebots and LLM agents for dozens of clients as a Top 1% Upwork freelancer: 50+ projects, 100% job success, rated 5.0/5. I then co-founded Source, where I lead engineering.

At Source we use AI agents to automate what used to take consultants months: migrating and connecting e-commerce and ERP systems.
