Worked on the Homebrew/homebrew-cask repository to expand platform support for Dyalog APL by updating its cask to version 20.0.52760, enabling compatibility with ARM architecture while maintaining legacy support for Intel systems. Focused on cask management and Ruby development, the approach ensured backward-compatible installations and reduced deployment friction for users transitioning to ARM-based hardware. The work was consolidated into a single, traceable commit, improving auditability and simplifying future maintenance. No major bugs were reported during this period, reflecting a careful and targeted engineering process that prioritized platform reach and smooth adoption of new architectures within the Homebrew ecosystem.
