Senior🎓
Top SchoolYuwei Zhang is a Staff Software Engineer with 17 years of experience, currently driving backend engineering at Meta from Menlo Park. A Carnegie Mellon MCDS graduate with roots at Fudan and UCSD, he blends production systems expertise with a strong data-science foundation. He has progressed through multiple engineering levels at Meta after interning at Facebook, shipping robust C++ and backend solutions at scale. An active open-source contributor to Facebook’s widely used folly library, he improved integer-arithmetic safety, constexpr utilities, and thread initialization primitives—work that quietly raises correctness and performance across many services. Colleagues rely on him for pragmatic, low-level improvements that prevent subtle runtime errors while enabling high-throughput systems.

Contributions summary:Yuwei contributed to the folly library by implementing and extending mathematical functions for integer arithmetic, specifically adding overflow-safe and clamped versions of addition and subtraction operations. They also added a mechanism, `InitThreadFactory`, that allows running initialization functions on newly created threads. Further contributions include adding and improving constexpr-related functions in the library, and adding utility functions for numeric conversion. These additions focus on improving the safety and performance of fundamental operations within the folly library.
