Worked on the LunarG/gfxreconstruct repository to improve build system stability and cross-platform reliability, focusing on Windows ARM64 and multi-architecture support. Addressed recurring build and configuration failures by refining CMake-based architecture detection and normalizing platform handling across different IDEs and input cases. Disabled AGS support on Windows ARM64 to prevent missing library issues, reducing linker errors and ensuring smoother CI and developer workflows. Leveraged expertise in CMake, build configuration, and cross-platform development to harden platform detection logic, resulting in more predictable builds and fewer environment-specific failures. The work emphasized robust engineering practices and targeted bug fixes over new feature development.
