Worked on the companieshouse/ch.gov.uk repository to stabilize the API Enumerations interface by reverting a recent subproject update, restoring the previous state without introducing new code changes to the main repository. This rollback was executed using Git for precise version control and ensured ongoing compatibility for downstream services that rely on the API. The approach prioritized risk reduction and operational continuity, with thorough documentation provided to explain the rationale and link the relevant commit for audit purposes. The work demonstrated disciplined change management and a focus on maintaining system stability, leveraging skills in Git workflows and API lifecycle management with JavaScript.
