Sam Hong is a Senior Application Security Engineer based in Irvine, California, with four years of hands-on experience bridging software development and security across startups and product companies. A UCSC computational mathematics graduate, he transitioned from full-stack and backend development roles—working with C#, .NET, React, SQL and cloud workflows—into application security at PayNearMe after engineering stints at Snyk and Fugue. He brings practical secure-by-design instincts from building transactional systems and e-commerce features to threat modeling, code-level hardening, and developer-focused security tooling. Comfortable moving between product teams and security programs, Sam pairs mathematical rigor with implementation experience to reduce risk without slowing delivery. An underrated strength is his background tutoring and cross-functional collaboration, which helps him translate complex security concepts into actionable guidance for engineers.
