Summary
🤩
RockstarScott Piriou is a pragmatic blockchain and systems engineer with eight years of hands-on experience building and optimizing low-level, security-sensitive software in Rust and Cairo. He has contributed to prominent open-source projects—Lighthouse (an Ethereum consensus client), Parity's Substrate, Ledger's Ethereum app, and OpenZeppelin Cairo contracts—focusing on performance, correctness, and developer ergonomics. Comfortable across firmware, backend services, and smart-contract implementations, he has shipped changes from Merkle/state-processing refactors to transaction signing UX and telemetry improvements. Scott blends a math-heavy academic background with practical hacking instincts from 42 Paris and has a knack for spotting automation opportunities early, previously turning a finance data task into a month-saved automation. Based in Paris, he now splits time between founding/startup work and contributing to on-chain governance tooling and ZK ecosystems.
