Worked on maintaining the Homebrew Cask for qBittorrent Enhanced Edition in the lizongying/homebrew-cask repository, focusing on artifact integrity and user security. Addressed a checksum mismatch by updating the SHA256 value for version 5.1.0.10, ensuring that macOS users receive untampered application downloads. The solution involved careful reconciliation of package metadata and a targeted Ruby commit to restore verification mechanisms. This work improved repository hygiene and traceability by documenting the fix in both commit history and changelog. Demonstrated skills in Homebrew, package management, and Ruby, with a focus on reliability and secure software distribution rather than feature development.
