About me
I started trying to make "businesses" in middle school, small stuff, using bots to buy limited edition clothes and sneakers, invested in BTC in 2017, shorted the French S&P 500 (CAC 40) during early-stage Covid, tried competition on COD and other side hustles...
I followed it into a Bachelor in Business Management at Paris School of Business, then realized the people actually building things were engineers. So I enrolled in the Computer Science Master's at 42 Paris, and I found my way.
While learning about segfaults and object-oriented languages, I founded 42Blockchain, the world's largest blockchain student club, connecting 2,000+ members of the 42 Network around blockchain. Organized 25+ events, partnering with the biggest ecosystem actors.
I mentored student teams building their first on-chain projects, secured grants to send them to hackathons in Brussels, Singapore, San Francisco, Bangkok, and helped them find their footing in an ecosystem that can feel pretty overwhelming at first. Closed six figures in sponsorships with Solana Foundation, Ledger, and others along the way.
I shoot photos on the side, travel whenever I can, and I'm currently building polyum.fun, a copy trading terminal on Polymarket.
Thriving for something that lives between dev and business, remote-first, with a reason to land in NYC every now and then.

Luma Bot
Apr 2025 – Nov 2025
AI-powered Luma event auto-registration
CLI that scrapes a Luma calendar or page and registers you to hundreds of events automatically. Uses Groq LLMs to fill RSVP fields from a short profile bio, so questions like "What are you building?" get a sensible answer per event instead of a copy-paste blob.

NYC
Really enjoyed NYC, similar to Paris, especially Soho and south Manhattan. Felt like the center of the world where things were happening.
