Rockstar🎓
Top SchoolLuis Ball is a founding software engineer based in San Francisco with seven years of experience shipping production web applications and building developer-facing features. He progressed from junior roles to senior engineer at imgix, focusing on reliable, secure front-end and tooling improvements before joining Juicebox (YC S22) as an early technical founder. Luis blends hands-on front-end expertise—demonstrated by contributions to the lightweight open-source drift library, where he improved CSP handling and build stability—with a strong emphasis on maintainability and security. He has a habit of catching subtle version and DOM regressions early, which keeps projects stable as they scale.

Outside work he’s a baseball fan and Tolkeinist, bringing curiosity and attention to detail to both code and hobbies.
