Summary
🤩
Rockstar🎓
Top SchoolHao Wei is a software engineer at Google with a decade of experience building reliable back-end systems and compiler toolchain features. A Zhejiang University MS graduate in computer science, he earlier interned with Microsoft Research Asia where he worked on text visualization and data mining—skills he continues to apply to engineering problems. His open-source contributions include substantive fixes and platform-specific runtime configuration work to the high-profile LLVM project, illustrating depth in low-level systems and cross-platform build reliability. Based in Mountain View, Hao combines research-minded problem solving with production-grade engineering, often tackling build and compiler issues that quietly keep large systems portable and maintainable.
