Worked on the companieshouse/ch.gov.uk repository, focusing on aligning dependency states through a targeted submodule update. Delivered a feature that updated the api-enumerations submodule reference, ensuring consistency across environments without altering the main repository’s codebase. This approach reinforced build determinism and reduced the risk of dependency drift, supporting future feature development that relies on the updated enumeration data. Demonstrated proficiency in Git submodule management and version control, applying best practices to maintain repository integrity. The work involved careful coordination of repository governance and dependency alignment, utilizing skills in Git and general software configuration management to enhance upgrade readiness.
