Rockstar🎓
Top SchoolManuel Aráoz is a founder and seasoned engineering leader with 13 years building distributed systems, financial technology, blockchain tooling, and AI-enabled applications from Uruguay. He co-led OpenZeppelin as Founder and CTO, contributing to widely used smart contract libraries and CLI tooling, and continues to drive product and technical strategy at his current venture, BUZHI. His hands-on background spans full-stack and backend work—contributing to high-profile open-source projects like Bitcore/Insight and OpenZeppelin—where he’s tackled everything from Bitcoin transaction internals to Solidity contract design. Comfortable moving between research areas (evolutionary computation, robotics, image processing) and production engineering, he’s known for blending deep technical rigor with practical, security-minded implementation. An unusual strength is his ability to refactor developer-facing tools and CLIs to improve usability while still advancing low-level protocol correctness.
