Top SchoolRomain Lefrancois is a seasoned full-stack technology leader and CTO with over a decade of experience designing and shipping web applications across fintech, healthcare, and public services. Based in San Francisco, he scaled from individual contributor to Chief Technology Officer at OneUp, where his distributed team powers banking-integrated business portals used by hundreds of thousands of customers. He blends hands-on engineering—working across Rails, React/Next.js, GraphQL and cloud tooling—with strategic product and team leadership. A builder since age 13, Romain continually experiments through his personal project InfinityBinge, which he rewrites to learn new stacks and operates at production scale (10k+ jobs/day ingestion). He’s equally comfortable optimizing backend data pipelines and crafting polished user experiences, bringing a pragmatic, curiosity-driven approach to solving real user problems.
