Worked on build system reliability and compiler infrastructure across Xilinx/llvm-project, Xilinx/llvm-aie, and llvm/clangir repositories, focusing on CMake-based configuration and system programming. Addressed critical build dependency issues in MLIR GPU-to-NVVM transformations by updating CMakeLists.txt, restoring toolchain stability. Improved build reliability in Xilinx/llvm-aie by introducing a file locking mechanism with FileLock.cmake to prevent race conditions during native builds, and resolved a libdevice module identification bug to suppress false MLIR warnings. Delivered a cross-compilation build fix for the mlir-irdl-to-cpp tool in llvm/clangir, ensuring correct dependency wiring. Work demonstrated proficiency in C++, CMake, LLVM, and build systems.
