Worked on the bdaiinstitute/spot_ros2 repository to enhance CI/CD reliability by updating GitHub Actions workflows. Focused on aligning the continuous integration environment with the development setup, the work involved pinning the Ubuntu runtime in YAML-based workflow files from ubuntu-latest to ubuntu-22.04. This adjustment addressed potential compatibility issues caused by upstream changes in the CI environment, improving build stability and maintainability. The update also enhanced traceability and auditability through clear documentation and process alignment. Leveraged skills in CI/CD and GitHub Actions, with a strong emphasis on YAML configuration, to ensure consistent and predictable development and testing workflows.
