Worked on packaging and release engineering for the lizongying/homebrew-cask repository, focusing on updating the Homebrew Cask formula for BlueBubbles to version 1.9.8. Used Ruby and Homebrew package management skills to implement a version bump and update the SHA256 checksum, ensuring users could securely install or upgrade to the latest release. Delivered these changes as a single, auditable commit, supporting traceability and integrity in the release process. The work enabled seamless distribution of the updated application through Homebrew, reducing friction for end users and maintaining high standards for package verification and reliability within the Homebrew ecosystem.
