Developed and delivered a new Homebrew-core formula for Rmux, a terminal multiplexer featuring a tmux-style command-line interface and daemon runtime. Focused on packaging the Ruby-based CLI tool for seamless installation and reliable operation across macOS environments, the work included implementing automated installation and testing procedures to ensure deployment consistency. By contributing directly to the Homebrew/homebrew-core repository, this effort enabled one-click adoption of Rmux for developers, reducing setup friction and expanding terminal multiplexing options. Demonstrated skills in Ruby, command line tooling, and package management, while strengthening packaging standards and release readiness for core-tap dependencies within the Homebrew ecosystem.
