Worked on improving Windows remote execution reliability in the facebook/buck2-prelude repository by addressing issues with symbolic links during C++ compilation. Introduced a copy_resources attribute to the sh_binary and python_bootstrap_binary rules, allowing resources to be copied instead of symlinked, which resolved Windows-specific build failures in remote execution environments. This solution enhanced build stability and ensured correct behavior on Windows CI systems. The work involved deep understanding of build systems, remote execution workflows, and Windows compatibility challenges, and was implemented using Python and Starlark. The contribution focused on bug fixing and infrastructure reliability rather than feature development during the period.
