Senior🎓
Top SchoolDonald Chai is a seasoned software engineer with 17 years of experience building performant, practical tools and systems from low-level libraries to large-scale products. Based in San Francisco, he has been at Google since 2016 and previously spent six years improving static analysis at Synopsys/Coverity, bringing a strong background in finding real bugs with fewer false positives. His open-source work includes optimizing ZIP handling in Android's system core (libziparchive), highlighting a knack for low-level performance tuning that reduces size and improves runtime behavior. Trained as an electrical engineer at Cornell and with a Ph.D. in EECS from UC Berkeley, he blends deep academic rigor with hands-on engineering and a history of accelerating EDA tooling as an intern early in his career. Colleagues rely on him to turn complex, system-level problems into reliable, efficient tooling that impacts production users.
