Summary
👤
Senior🎓
Top SchoolAlex Yu is a Staff Software Engineer with 11 years of experience building backend platforms and care-delivery systems at Oscar Health, where he has progressed from intern to technical lead and now shapes production services at scale. He is fluent in Python, Go, and JavaScript and routinely architects systems using Kubernetes, gRPC, Kafka, and a mix of relational and search datastores. Alex combines strong engineering rigor from a Columbia magna cum laude background in mathematics and computer science with hands-on ownership of critical subsystems like secure messaging, e-prescribing, and call services. He favors pragmatic technology choices and is comfortable adopting new tools to solve domain-specific problems. Colleagues rely on him for designing resilient, data-driven services that improve patient and member experiences across complex healthcare workflows. A detail that often surprises peers: he began at Oscar implementing an RPC call service as an intern and has iteratively expanded that operational mindset into leading platform-wide care delivery infrastructure.
