Worked on release management and version control for the NHSDigital/e-referrals-service-patient-care-api and NHSDigital/e-referrals-service-api repositories, focusing on semantic versioning and deployment readiness. Delivered three feature updates by incrementing API versions to support new features and maintain compatibility across downstream integrations. Emphasized clear commit traceability and governance by aligning release notes and configuration files, ensuring minimal risk during deployment. Utilized Git for version control and configuration management, with a strong focus on process reliability rather than direct code changes. The work prioritized stability, future-proofing, and streamlined integration, supporting ongoing development and reducing compatibility risks for dependent systems.
