Worked on the lizongying/homebrew-cask repository to deliver native Apple Silicon (arm64) compatibility for the Sejda PDF cask, focusing on improving installation workflows for macOS users. The engineering approach involved updating packaging logic in Ruby to include architecture-specific checksums and dynamic URL handling, thereby removing the Rosetta dependency and streamlining the user experience. Emphasis was placed on maintainability and future-proofing the cask against evolving macOS requirements. This work leveraged expertise in Homebrew Cask and macOS application packaging, resulting in reduced installation friction, broader compatibility for Apple Silicon devices, and a more robust deployment process for end users.
