Worked on reliability and safety improvements in C++ codebases, focusing on bug fixes rather than feature development. In the shader-slang/slang repository, addressed a safety-critical issue by refactoring the SlangUUID equality operator to use direct member-wise comparison, eliminating undefined behavior from reinterpret_cast and union usage and ensuring C++ standard compliance. In microsoft/PowerToys, improved the stability of PowerRename by replacing a union with direct FILETIME handling in the PutFileTime function, mitigating undefined behavior and enhancing time comparison reliability. Demonstrated strong debugging, system programming, and software engineering skills while prioritizing maintainability, code quality, and cross-platform correctness throughout both projects.
