Summary
🤩
Rockstar🎓
Top SchoolXiao Hang is a seasoned software engineer with 11 years of experience based in San Jose, currently applying deep backend expertise at Google. He has contributed to high-profile open-source projects like Protocol Buffers and gRPC, adding Java Nano proto support and enhancing secure OkHttp transport to enable efficient, compact messaging and secure RPCs. His work reflects a focus on practical interoperability and performance in data interchange and mobile/Android scenarios, including improvements to examples that help adopters get started. A Sun Yat-sen University computer science graduate, he blends core protocol-level engineering with hands-on integration and maintenance, often bridging generator code and runtime plumbing. Less obvious: he’s comfortable making small but impactful changes—package naming conventions and build flags—that ripple across large ecosystems.
