Contributed to Homebrew-core by developing and enhancing package formulas focused on build systems and cross-platform support. Delivered a feature update for the dsda-doom formula, improving dependency management by replacing and adding libraries, and strengthening build reliability through CMake’s STRICT_FIND and pkgconf integration. Later, introduced the SDL3_net formula, implementing a cross-platform TCP/IP socket wrapper with installation instructions and automated verification tests to ensure runtime reliability. Work emphasized robust package management, testing, and maintainability within the Homebrew-core repository, utilizing Ruby and CMake to streamline installation and verification processes while reducing the risk of future breakages during package upgrades.
