Ben James enhanced the hmcts/rd-caseworker-ref-api by introducing the WLU Administrator role, implementing backend logic, database migrations, and integration tests to ensure robust role-based access control and reduce manual configuration errors. Using Java, SQL, and integration testing, he validated end-to-end propagation of the new role, minimizing misassignment risks across the platform. In the hmcts/ccfr-fees-register-admin-web repository, Ben addressed security vulnerabilities by upgrading Axios and updating dependency locks, maintaining stability and security in the admin web UI. His work demonstrated careful attention to integration, security patching, and dependency management, delivering targeted improvements within a focused two-month development period.
