Building, shipping, signing.
I build sovereign-grade infrastructure for regulated industries — and run four ventures that ship it. One filed patent. Hundreds of professionals served daily.

Four ventures. One operator.
I don't consult from the sidelines — I co-found, run engineering, and ship. Here's what I operate today.
DIV Protocol
1 filed patent · hundreds of pros daily
Sovereign encrypted cloud for regulated industries — blockchain + post-quantum encryption, incubated at Télécom Paris. Selected to represent French sovereign tech at Bercy (Mar 2026).
RD-Agency
$90M peak token mcap
A 10-engineer Web3 / AI / full-stack studio. Shipped for Nike RTFKT, Capgemini, Vinci, Alpha Blue Ocean.
Alesia RSVP
200+ conferences · 30+ countries
Global event production with embedded crews in SF, NY, Tokyo, Sydney, Paris, Dubai — plus a 100+ Paris crypto community.
Cristal — EPITA
€200K / 18 months
Revenue generated
Led EPITA's Junior-Entreprise — €200K generated over 18 months across 50+ IT projects for Société Générale, AXA, Thales, Safran.
The sovereign cloud, built right.
Regulated industries can't put sensitive data on someone else's cloud. DIV Protocol gives them sovereign, encrypted infrastructure they actually own — and I architect it end to end.
Renting cloud infrastructure means handing your data to a third party and hoping their compliance posture matches yours. For law firms, financial institutions, and defense-adjacent clients, that's not a trade-off — it's a liability.
DIV Protocol flips the model: you own the keys, the nodes, and the audit trail. No shared tenancy, no vendor lock-in, no ambiguous data residency. Infrastructure that is legally and cryptographically yours.
I designed the architecture from first principles — post-quantum encryption layered with blockchain anchoring — and turned it into a patent. Then I built the team and the product around it.
Post-quantum + blockchain-anchored. Patent FR2602936, authored and filed.
Serves hundreds of legal & regulated professionals every day.
Incubated at Télécom Paris. Selected for the Ministry of Economy (Bercy), Mar 2026.
I lead 10+ across engineering, product, and design.
Need it built? RD-Agency ships it.
My Web3, AI & full-stack studio — 10 engineers who design, build, and deploy production systems for enterprises and crypto teams.
Smart Contracts
Solidity & Rust. Gas-optimized, audited, multi-chain.
Full-Stack Engineering
Next.js, NestJS, Postgres. Prototype to production.
AI Integration
LLM agents & automation wired into real products.
Custom Web3 Platforms
Tokenomics, dApps, NFT systems — end to end.
Have a project? I scope it personally.
Direct line — no account managers, no back-and-forth. Just results.
An operator, not a résumé.
I'm a founder and engineer in Paris who builds at the intersection of cryptography, software, and execution. I'd rather show a filed patent and a platform serving hundreds of pros daily than list job titles. Across DIV Protocol, RD-Agency, Alesia RSVP, and Cristal, the constant is the same: take the hard infrastructure problem, build it from zero, and ship it to people who can't afford for it to fail.
Who I build for.
Enterprises, listed companies, and category leaders — across deep tech, finance, and Web3.
