Rockstar🎓
Top SchoolGarrett Gu is a software engineer with a decade of experience building runtime and infrastructure systems, currently working on builds infrastructure at Anthropic in New York. He has deep systems and security expertise demonstrated by contributions to Cloudflare’s Workers runtime and Wrangler CLI—helping ship the first iteration of Python Workers via Pyodide and improving V8/Wasm performance and memory handling. His background spans practical cryptography and tooling (Plaid KMS, cert rotation), reverse-engineering and deobfuscation (Hex-Rays), and applied ML/NLP prototypes (Apple), giving him a rare blend of low-level runtime, security, and applied research skills. He’s an active open-source contributor who cares about developer ergonomics and reproducible build/artifact systems, and his teaching experience at UT Austin underscores strong communication and mentoring abilities.
