Luke worked on the EngFlow/example repository, focusing on modernizing the build system and continuous integration workflows. He rebranded the build configuration from magnesite to pyrite, updating references within the .bazelrc file to standardize naming without altering functionality. Additionally, Luke migrated the CI platform to use macOS ARM64-only builders, removing legacy x86_64 support to align with evolving hardware requirements and streamline maintenance. His work leveraged Bazel, Shell, and YAML, emphasizing build system configuration and CI/CD best practices. These changes improved maintainability and efficiency, laying a foundation for future enhancements while minimizing risk from outdated configurations and redundant complexity.
