Worked on registry modernization and error handling across jdx/mise and Homebrew/brew repositories. In jdx/mise, standardized tool provisioning by adopting Universal Build Image as the backend, replacing asdf references, and expanding the registry with nine new tools to streamline onboarding and ensure consistency across development and CI environments. In Homebrew/brew, refactored the Brew Services List command to handle error codes and process IDs correctly, while removing unnecessary systemd dependencies from tests to improve reliability and portability. Demonstrated skills in configuration management, Ruby development, and command-line tooling, with contributions focused on automation, error handling, and system administration workflows.
