Rockstar🎓
Top SchoolHunter Goldstein is a Senior Software Engineer with 11 years of experience building language runtimes and systems-level infrastructure, currently contributing to Luau at Roblox. He has deep expertise in compiler and VM work from his time on Meta’s Hack language and HHVM—driving typed systemlib migrations, declaration-driven bytecode efforts, and runtime-safe rollouts—and has improved core VM behaviors in a high-profile open-source project. Hunter also brings OS and robotics experience from Zoox and the Cornell Mars Rover team, showing a practical blend of embedded, safety-critical, and developer tooling work. He’s comfortable refactoring complex parsers and shells as shown by contributions to redox-os/ion, and pairs rigorous academic roots in formal verification with hands-on production delivery. Based in Redwood City, he favors shipping robust, type-safe systems that reduce runtime failures and scale across large codebases.
