Worked on the NixOS/nixpkgs repository to deliver Darwin driver support for the kmonad Haskell package, enabling macOS functionality by introducing a darwinDriver passthru attribute that leverages the karabiner-dk package. Focused on package maintenance and management using Nix and YAML, ensuring dependencies remained current by upgrading karabiner-dk from version 6.3.0 to 6.4.0. Improved maintainer tracking by adding auscyber as the kmonad maintainer, supporting better long-term package stewardship. The work emphasized system administration and configuration, with targeted commits that aligned with cross-platform goals and maintained stable release hygiene throughout the development cycle.
