Worked on the operaton/operaton repository to deliver a CI nightly build optimization that introduced change-detection logic into the pipeline. Developed a GitHub Actions workflow using YAML to check for code changes within the last 24 hours, enabling the system to skip nightly builds, integration tests, and release steps when no updates were detected. This approach reduced unnecessary CI resource consumption and improved feedback speed for the team. The work demonstrated practical application of CI/CD automation, pipeline gating, and Git-based workflow hygiene, addressing inefficiencies in nightly execution and contributing to a more deterministic and efficient continuous integration process.
