Worked on the hmcts/pcs-api repository to deliver end-to-end Case Linking and Proposals Management, enabling creation, management, and display of case links within the system. Focused on enhancing the underlying data model by introducing new link tables and implementing versioning through database migrations, ensuring reliable and traceable linkage across cases. Utilized Java, SQL, and Spring to build robust API endpoints and support seamless integration between the user interface and backend. The work emphasized safe handling of proposed linked cases, allowing for streamlined review and management. Collaborated on migration scripting to support these features, prioritizing data integrity and maintainability throughout development.
