Rizal Fadlullah delivered a cross-platform enhancement to the Homebrew/homebrew-cask repository by adding Linux support for the android-commandlinetools cask. He implemented OS-specific SHA256 checksums and download URLs, ensuring Linux users could access and verify Android CLI tool assets alongside macOS and Windows users. Using Ruby for cask development, Rizal updated packaging logic to expose Linux assets and maintain consistent update paths across platforms. He integrated these changes with existing CI pipelines to validate asset integrity and prevent regressions. This work expanded platform coverage, reduced friction for Linux users, and demonstrated a solid understanding of cross-platform support and Ruby programming.
