Worked on macOS application deployment and package management by maintaining and enhancing Homebrew casks in the lizongying/homebrew-cask and Homebrew/homebrew-cask repositories. Delivered a new cask for OpenChamber 1.10.1, enabling streamlined installation and update workflows for macOS users by updating Ruby scripts and removing deprecated livecheck blocks. Upgraded the Miro Desktop cask to version 0.9.78, ensuring users received the latest release with minimal disruption and no functional code changes. Focused on reliability and maintainability, the work leveraged Ruby and cask management skills to keep application packaging current and aligned with evolving update mechanisms in the Homebrew ecosystem.
