Rockstar🎓
Top SchoolSantiago Pastorino is a seasoned software engineer and co-founder with 17 years of experience building robust systems and leading teams from Montevideo, Uruguay. As WyeWorks' Rust team lead and an active contributor to the Rust compiler, types team, Clippy and Polonius, he navigates deep compiler internals and borrow-checker algorithms while shipping practical tooling. His open-source footprint spans high-impact projects across ecosystems—Rust core repos and popular Ruby projects like Rails, Devise, Puma and Bundler—showing fluency in both low-level systems and web platforms. He combines production-minded performance work (Puma, Rack) and security-aware auth fixes (Devise) with rigorous test and refactor contributions (mio, rust-by-example). Notably, he blends startup leadership with hands-on compiler engineering, a rare mix that helps bridge product needs and language-level correctness. Trained in computer science engineering at Universidad de la República, he pairs academic grounding with long-running entrepreneurial and engineering practice.
