Addressed symlink creation issues during installation, ensuring a smoother post-install setup and reducing friction for users integrating ARM toolchains. Leveraged expertise in Ruby and Cask Management to enhance packaging stability, which minimized installation errors and support overhead. Maintained clear documentation and commit traceability to support future maintenance and updates. The work centered on delivering a consistent, up-to-date ARM GCC toolchain experience within the Homebrew ecosystem, utilizing Homebrew’s infrastructure and Ruby scripting capabilities.
