During January 2026, Nick Thomas focused on improving build stability for OCaml projects in the Buck2 and Buck2 Prelude repositories. He addressed recurring build failures caused by linker command lines exceeding the system ARG_MAX limit during LTO linking. By developing a unified strategy that writes linker arguments to a response file and passes them to the linker, Nick reduced the risk of 'argument_list_too_long' errors. This approach, implemented using OCaml and Python, enhanced CI reliability and enabled larger builds. His work demonstrated depth in build system development and linker optimization, directly improving the robustness of OCaml build pipelines for large codebases.
