Worked on build optimization for the espressif/llvm-project repository, focusing on streamlining the DXIL-Dis build process. Refined the DirectXShaderCompiler cloning workflow by excluding tests and unnecessary dependencies, which reduced both clone size and build time. This approach improved repository hygiene and made builds more reproducible, directly benefiting continuous integration pipelines by lowering resource usage. Demonstrated skills in build system configuration using CMake, along with expertise in Git-based repository management and CI optimization. The work emphasized careful dependency management and efficient build tooling, resulting in a more maintainable and efficient development process without introducing new bug fixes during the period.
