Worked on modernizing the ONNX-MLIR transformation pass infrastructure within the onnx/onnx-mlir repository, focusing on improving build stability and code quality. The approach involved separating kernel transformation passes into dedicated TableGen files and realigning dependencies to ensure correct compilation order, which reduced build-time errors and clarified transformation boundaries. Applied clang-format across the codebase to enhance style consistency and support more reliable continuous integration. Leveraged C++, MLIR, and compiler design expertise to streamline the integration pipeline, enabling faster iteration and reducing risk in downstream workflows. The work emphasized maintainability and safer compilation practices without introducing new bug fixes during the period.
