Developed and delivered the Zapp command-line tool, enabling users to flash ZSA keyboards such as the Moonlander, Voyager, and Ergodox directly from the terminal. The project involved implementing the Zapp CLI in Ruby, focusing on seamless device integration and automation of keyboard customization workflows through Oryx. Packaged as version 1.0.0 and contributed to the Homebrew/homebrew-core repository, the tool streamlined installation and usage for end users. Work included writing comprehensive client-facing documentation and a promotional blog post to guide adoption. The effort emphasized command line tooling, software installation processes, and integration with existing keyboard management platforms.
