Worked on the bemanproject/infra repository to enhance build system reliability and maintainability over a two-month period. Focused on refactoring CMake install logic, reorganizing FetchContent usage, and renaming install components to improve clarity and reduce ambiguity in the build process. Developed a centralized CMake helper function, beman_install_library, to standardize the installation of library targets, headers, and optional configuration files across multiple repositories. These changes streamlined onboarding, reduced code duplication, and improved CI stability. The work demonstrated strong skills in build systems, CMake, and library management, with an emphasis on architectural improvements and automation rather than bug fixing.
