Rockstar🎓
Top SchoolLewis Liu is a founder and frontend-focused engineer with 11 years of experience building customer-facing products and developer platforms in San Francisco. He led early frontend efforts at Brex as employee #15, shipping critical onboarding and rewards experiences and establishing long-lived frontend infrastructure patterns like Apollo normalization, CSS-in-JS, and visual regression testing. Before founding Reflame he helped migrate CircleCI’s ClojureScript frontend to a modern, typed JavaScript stack and introduced tooling to improve developer velocity and reliability. An active open-source contributor, Lewis has improved frontend stacks for projects like Highlight.io and added mobile OAuth flows to remotestorage.js, showing a comfort across both web and mobile ecosystems. He combines pragmatic product instincts with a history of platform-level decisions that scale engineering teams, and prefers incremental, low-risk migrations over risky rewrites. Based in SF with a Waterloo software engineering background, he blends startup execution experience with hands-on implementation.
