During October 2025, S. Khaw worked on the companieshouse/ch.gov.uk repository, focusing on stabilizing the API Enumerations subproject. By reverting the subproject to a previous commit, S. Khaw restored a known stable state without introducing new code changes to the main repository. This rollback, managed through disciplined use of Git and careful documentation, preserved API compatibility and minimized risk for downstream services relying on Java-based integrations. The work demonstrated a methodical approach to change management, ensuring that dependent teams could proceed with confidence while maintaining auditability and traceability of the rollback decision within the project’s version control history.
