Scientist-turned-engineer. Fifteen years in molecular biology (MSc.) and environmental engineering (MEng.) across France 🇫🇷, Canada 🇨🇦 and Switzerland 🇨🇭 — building fullstack software since 2022.
Currently Full-Stack Engineer at Prismo.io (Next.js / TypeScript, CQRS, hexagonal architecture, Supabase). Recent personal work: three end-to-end DApp case studies on Base and Ethereum Sepolia — Solidity + Foundry, Chainlink oracles, durable LangGraph + Inngest agents — and one full-stack Web2 auction platform.

Peer review as a trust-minimised coordination game — deployed on Base Sepolia & Ethereum Sepolia.
- Authors stake ETH; a LangGraph submission agent screens for plagiarism (Exa AI + Gemini); Chainlink VRF selects reviewers from the staked pool; human verdicts settle on-chain via EIP-712 signatures; research artifacts pinned to IPFS.
- Durable orchestration: Inngest
step.run+ LangGraph checkpointers carry multi-day human-in-the-loop review across serverless cold starts. - Alchemy Notify webhooks (HMAC-SHA256) project contract events into Neon Postgres (Drizzle) via optimistic concurrency; viem WebSockets + TanStack Query drive the live UI.
- 50 Foundry tests across 12 suites — 100% lines / statements / branches / functions.
Oracle-driven settlement with time-weighted payouts — Ethereum Sepolia.
- Chainlink Automation calls
performUpkeepto resolve rounds at deadline without operator intervention; settlement reads Chainlink Price Feeds. - Chainlink VRF v2.5 for unpredictable ERC-1155 reward token IDs; a Tenderly Web3 Action bridges resolution events to a role-gated mint. CEI pattern + OpenZeppelin
nonReentrantonclaimReward.
Atomic burn–mint composition with 100% Foundry coverage on project-owned contracts.
- Separate rules contract (Forge) vs ledger (FToken) with immutable ownership; composite IDs 3–6 minted via atomic
burnBatch+mintin a single transaction. Cooldown-gated basic mints (IDs 0–2). - Event-driven Next.js UI with wagmi, Alchemy WebSockets and TanStack Query.
Real-time bidding with automated lifecycle and Stripe payments — full Web2 stack.
- Supabase Realtime for live bids, CRON-triggered Edge Function for scheduled auction closure, Stripe webhooks for async payment state.
- i18n FR / EN / DE (Lingui), URL-driven filters (nuqs), TanStack Table, Recharts dashboards, Jest tests.

Before software: environmental remediation project management (KIBAG, SERPOL, SITA/SUEZ — France & Switzerland) and genomic research (INSERM France, University of British Columbia). The habit of designing controlled experiments and stress-testing hypotheses transfers directly to smart-contract security and agent reliability.
