Worked on the KhronosGroup/Vulkan-ValidationLayers repository to enhance build reliability and maintainability for Windows environments. Focused on standardizing platform detection by replacing the non-standard WIN32 macro with the industry-standard _WIN32 across the codebase, addressing inconsistencies that affected cross-file and CI builds. Utilized expertise in build engineering, C++, and Python to implement these changes, ensuring that future Windows-specific checks are more portable and easier to maintain. The work involved fixing a macro issue that previously led to unreliable builds, laying the groundwork for more robust platform detection and contributing to the overall stability of the build process.
