Rockstar🎓
Top SchoolRick Hanlon is a seasoned front-end engineer with 13 years of experience, currently working on React Core at Facebook and previously on React Native. He combines deep product-facing UI work with infrastructure-level contributions—improving Metro, Relay, Jest, and Create React App to enhance developer experience and reliability. His background spans engineering leadership at Kustomer and senior web roles at SeatGeek, giving him product-minded instincts alongside hands-on coding. A mathematics graduate with a minor in CS, he often gravitates toward testing, tooling, and documentation improvements, and has contributed to high-profile projects that shape the React ecosystem. An atypical detail: he bridges both web and native toolchains, regularly touching bundlers, source maps, and test automation rather than only UI components.
