Rockstar🎓
Top SchoolSantiago Palladino is a Principal Engineer with 17 years of software experience and a deep specialty in Ethereum tooling, privacy rollups, and backend architecture. Based in Buenos Aires, he currently contributes to Aztec Labs’ zero-knowledge rollup and serves on The Graph Council, blending protocol governance with hands-on development. A polyglot generalist whose day-to-day stack is TypeScript and Solidity, he has led product and engineering efforts at OpenZeppelin—shipping Defender and improving core upgradeability and security tooling used across the ecosystem. He’s an active open-source contributor (notably to Gas Station Network and OpenZeppelin repos), authored the book "Ethereum for Web Developers," and mentors early-stage crypto teams on security and operational best practices. Colleagues describe him as equally comfortable designing infra and UX, and as someone who turns complex cryptographic primitives into practical, production-ready systems.
