Worked on the tempoxyz/tempo repository to enhance the macOS installer by automating libusb dependency installation using Bash and Shell Scripting. Addressed the issue of silent install successes on clean macOS systems by integrating Homebrew-based dependency checks and adding a post-install verification step to ensure binaries launch correctly. Developed comprehensive regression tests and implemented CI/CD pipelines to validate installation flows across both macOS and Linux environments. Improved installer reliability by refining gating logic to prevent false-positive validations and reduced code complexity by trimming the patch size. The work focused on maintainability, cross-platform compatibility, and robust dependency management for end users.
