Worked on the lizongying/homebrew-cask repository to enhance package management for macOS applications using Ruby and DevOps practices. Developed a new Homebrew Cask for Antinote, providing comprehensive metadata such as versioning, download URL, and system requirements to streamline deployment and ensure compatibility. Addressed a user-facing stability issue by updating the PopClip livecheck process to ignore beta updates, thereby restricting installations to stable releases and improving update reliability. Maintained clear, auditable commit history to facilitate code reviews and future rollbacks. Demonstrated attention to quality and maintainability while leveraging expertise in Homebrew, package management, and macOS application deployment.
