Summary
👤
Senior🎓
Top SchoolWilliam Y is a software engineer with roughly a decade of experience building backend systems and cryptographic tooling, currently applying his skills at DoorDash after contributing to AWS's CryptoPALs and FIPS efforts. He holds both BS and MS degrees in Computer Science from WPI (2022) and has deep hands‑on experience automating ACVP/FIPS validation workflows, coordinating with third‑party labs, and maintaining FIPS-capable crypto libraries. As an intern he designed a platform-agnostic benchmarking framework for AWS-LC—integrating OpenSSL/BoringSSL tooling, CI/CD automation, EC2 runners, and S3 result storage—which remains an active open-source effort in a widely used AWS cryptography repo. Beyond crypto, he has built ML proof‑of‑concepts for image colorization and super-resolution, and he’s an avid car and gaming enthusiast who brings practical curiosity to complex engineering problems.
