Worked on the LizardByte/Sunshine repository to enhance Arch Linux packaging by introducing greater flexibility and efficiency in the build process. Refactored the PKGBUILD script using Bash and shell scripting to enable optional CUDA support and unit-test builds, controlled through environment variables. This approach reduced unnecessary dependencies and build times for standard installations while preserving advanced functionality for specialized use cases. The changes improved maintainability and allowed for easier configuration in continuous integration environments. Demonstrated skills in build systems, packaging, and environment-driven feature toggling, resulting in a more scalable and adaptable deployment workflow for the project’s Arch Linux users.
