Worked on the lizongying/homebrew-cask repository, focusing on maintaining the integrity and reliability of the JProfiler cask within the Homebrew Cask ecosystem. Addressed distribution security by updating the SHA256 checksum for the JProfiler package, ensuring that downloads remained authentic and untampered. Employed Ruby and Homebrew Cask Management skills to implement these changes with clear, traceable commits and thorough documentation, supporting auditability and future maintenance. This work prevented installation issues related to checksum mismatches and aligned repository practices with Homebrew standards, ultimately enhancing user trust and reducing support overhead by maintaining high standards for software distribution hygiene and metadata accuracy.
