Edward Phillips focused on enhancing security in the SwanseaUniversityMedical/DARE-Control repository by addressing a role-based access control issue. He implemented a visibility gate for the 'New TRE' button, ensuring only users with the 'dare-control-admin' role could access this administrative feature. Using ASP.NET Core and front-end development skills with C# and cshtml, Edward’s solution reduced the risk of unauthorized actions and aligned the application with governance requirements. The work was delivered as a targeted bug fix, with clear commit messaging and traceability to issue #936, demonstrating a precise and security-conscious approach to RBAC hardening within the project’s codebase.
