Rockstar🎓
Top SchoolBenoit Girard is a software engineer with 16 years of experience specializing in web infrastructure and performance, currently building core infrastructure at Meta for the React & Relay–powered Facebook site. He previously led performance engineering at Facebook—rewriting module loaders, shipping dynamic code loading, and proposing CSS-level features—and before that designed major graphics and responsiveness features in Firefox at Mozilla. Benoit contributes to high-profile open source projects (React, the CSS Working Group drafts, and a record-and-replay debugger), blending browser internals, frontend tooling, and backend systems. Based in Menlo Park with a Waterloo software engineering degree, he pairs deep low-level systems knowledge with product-focused optimization and a knack for turning specification ideas into shipped improvements. An unusual strength is his track record of moving browser-spec proposals into real implementations, bridging standards, engine internals, and production web performance.
