Worked on the bazelbuild/rules_cc repository to enhance Windows build determinism and reliability by implementing an MSVC determinism feature. Focused on applying the /Brepro flag not only during compilation but also at the linker stage, ensuring consistent and reproducible builds across C and C++ projects. Integrated changes from Copybara-imported pull requests to maintain traceability and reproducibility throughout the build pipeline. Leveraged expertise in C/C++ development, build system configuration, and Python to align linking behavior with object compilation, reducing nondeterminism in multi-language scenarios. This work contributed to more stable CI processes and simplified troubleshooting in Windows development environments.
