Senior🎓
Top SchoolSean Fong is a software and design engineer with eight years of hands-on experience building front-end products and tooling, now focused on agent behavior monitoring as a Founding Member of Technical Staff at Judgment Labs in San Francisco. He brings a practical full-stack background from internships and roles at Corsair and multiple leadership and web roles at UC Irvine, where he combined student governance, research assistance, and web production. Sean’s work blends product-minded front-end development with systems thinking, shipping user-facing interfaces and monitoring solutions for complex agent behaviors. He has a track record of quickly moving between roles—webmaster, tutor, grader, and project lead—demonstrating an ability to learn, document, and operationalize systems in academic and startup settings. Based in the Bay Area and trained in computer science at UC Irvine, he pairs strong UI/UX sensibilities with an interest in observable, auditable agent systems. Notably, his background shows a pattern of building tooling and process around products, not just features, which helps teams scale engineering and design practices.
