Rockstar🎓
Top SchoolGuy Bedford is a Principal Systems Engineer with 14 years of experience building robust JavaScript tooling and runtimes, currently at Cloudflare and a longstanding TC39 delegate. He is a prolific open-source maintainer—known for deep contributions to Babel, Rollup, SystemJS and Node.js module loading—and the author of es-module-shims and numerous interoperability tools that helped shape modern ES module semantics and import maps. His work spans front-end plugins to low-level runtime loaders and Wasm bindings, combining compiler-level transformations with practical build-system engineering. An Oxford-trained mathematician, he brings rigorous problem-solving to complex edge cases (for example, nuanced URI and encoding fixes across runtimes) and a track record of shipping production-ready optimizations and tests across major projects like Rollup, Next.js and Node.
