Worked on the hmcts/pcs-api repository to enable and stabilize management of data definitions within the PCS API pipeline. Developed an initial feature allowing definition file uploads in the master pipeline by introducing a new function call and configuring environment variables to interact with the definition store and case API in AAT environments. After deployment, reverted the change to maintain pipeline stability while preserving CI/CD governance for data definitions. The work focused on CI/CD and DevOps practices, leveraging Jenkins and Groovy to ensure that data definition management could be governed through automated pipelines without compromising the reliability of the deployment process.
