Senior🎓
Top SchoolHao Tong is a Senior Software Engineer at Google with 12 years of experience bridging systems research and production storage and database performance. He earned a Ph.D. from the University of Chicago where his kernel-level work produced systems like Tiny Tail Flash, MittOS, and FEMU that tackle tail latencies and emulation for flash storage. At Google he focuses on storage, analytics, and hardware/software performance, bringing an academic rigor to production engineering. Hao contributes to open-source tooling such as enhancements to the CWL reference implementation, emphasizing traceability, type safety, and maintainability. His background in multi-layer cache policies and large-scale pipeline analysis gives him unusual depth in both low-level OS/kernel modifications and end-to-end data platform performance. Based in Sunnyvale, he combines research-driven innovation with hands-on engineering to reduce real-world tail latency and improve SLO-aware behavior.
