Worked on the Xilinx/XRT repository to enhance build reproducibility and security compliance for Windows development environments. Delivered deterministic builds for xrt-smi and xrt libraries by refining CMake configurations and localizing MSVC linker flags, ensuring consistent binary outputs across builds. Addressed security vulnerabilities by updating compiler options to enforce cast guards, enable fast-fail on violations, and activate whole-program optimization, all validated through local builds and binary comparisons. Focused on maintainability by documenting changes and aligning with BinSkim compliance requirements. Utilized CMake, MSVC, and compiler optimization techniques to support stable release pipelines and reduce nondeterminism-driven debugging and security risks.
