Justin Chan is a Software Engineer III at Google with 11 years of experience building backend systems and machine learning applications, grounded in a University of Waterloo CS education. He has a strong track record across major platforms—Microsoft, Meta, Shopify—and early deep learning work deploying computer vision models for retail at Focal Systems. Justin blends infrastructure and ML experience, having improved large-scale async job quota systems at Meta and shipped performance-critical front-end and CI tools at Shopify. At Google he continues to operate at the intersection of reliable backend services and applied ML, moving research prototypes into production. Notably, he has a history of independently identifying and fixing recurring reliability issues and shipping open-source tooling (e.g., an HTML linter) that scaled across teams.
