Summary
🤩
Rockstar🎓
Top SchoolBrian Kelley is a seasoned software engineer with 12 years of experience specializing in end-to-end iOS and macOS app development, notable for building the first Word for iPad and modernizing Office UI across platforms. He blends deep systems and compiler knowledge—contributing fixes to clang/LLVM around Objective-C weak references—with hands-on mobile SDK and platform integration work at Meta and Microsoft. As a principal engineer he designed accessibility and React Native macOS strategies that became long-lived foundations, and as an engineering lead he shipped large UI migrations and tooling that caught hard-to-find bugs. Comfortable across Swift, Objective-C, and C++, he pairs language/runtime expertise with practical shipping instincts that favor pragmatic compatibility solutions over risky rewrites. Based in Bellevue, WA, he’s the kind of engineer who can both fix subtle compiler semantics and deliver delightful, production-grade user experiences.

Contributions summary:Brian primarily focused on enhancing the clang compiler's Objective-C and Objective-C++ support, specifically related to the handling of weak references and type traits. Their work involved modifying the compiler's internal logic to correctly classify classes with weak members, ensuring proper behavior during copy, move, and destruction operations. They also addressed and fixed issues related to the use of `__weak` in type traits, ensuring correct behavior of type traits like `__has_trivial_assign`, `__is_pod`, and similar traits. Finally, they fixed bugs related to `-Warc-repeated-use-of-weak` warning and improved the integration of weak references within the compiler.
