Freelance Blockchain
Engineer
I help companies, banks and Web3 teams ship blockchain products that work, and understand what is really happening on-chain.
Full remote, worldwide · Hybrid Marseille – Paris
My Master's in Computer Science at ESGI Paris (blockchain track) included dedicated courses in monetary economics and credit. I understand banking and financial stakes beyond the purely technical side, and I've already worked on the subjects that matter there: stablecoin bridge design for Etherlink, Aroha (a tokenized fund aggregator, prize winner at ETHGlobal Bangkok 2024), a real-world asset tokenization prototype, on-chain fund tracing for compliance.

Non-custodial cross-runtime wallet (Chrome extension + mobile app) letting a single Tezos X account interact with both Michelson and EVM runtimes. Lead developer from proof of concept to MVP: encrypted vault and local signer, EIP-1193/EIP-6963 dApp connectivity, WalletConnect v2, cross-runtime transaction routing. Hexagonal architecture sharing ~85% of the core between extension and mobile, 520+ unit tests, Playwright E2E suite in CI.

I'm Antony, a blockchain engineer based between Paris and Marseille, France, working full remote with clients anywhere in the world.
I spent two years at Nomadic Labs, the core team behind Tezos, building products and tooling for Tezos, Tezos X and Etherlink.
I was the lead developer of the Tezos X Wallet, smart contracts in Solidity and CameLIGO, protocol research (intent-based systems, cross-chain messaging, privacy chains) and hands-on support for teams deploying on Tezos and Etherlink. In 2026 I went freelance to bring that experience to a wider range of projects.
I finished my Master's in Computer Science at ESGI Paris in 2026, on the blockchain track, with courses in monetary economics and credit alongside the engineering. That's why I'm as comfortable talking to a bank's compliance team as to a protocol's core developers.
What drives me is understanding how things really work under the hood: reverse-engineering a DeFi protocol, debugging a low-level issue, or spending a weekend at a hackathon testing an idea. Two of those weekends ended with prizes, at ETHGlobal Bangkok 2024 and Chiliz Hacking Paris, and one of them grew into Predcast.
Tell me about it, even a rough idea. I'll come back within 24 hours with a clear view of what's feasible.
