Over a three-month period, contributed to DEFRA’s epr-payment-service and epr-payment-frontend by delivering three new features focused on payment processing and user experience. Developed and enhanced APIs using C#, ASP.NET Core, and Entity Framework Core, including an Accreditation Fee Management system and a backward-compatible Online Payment Insertion API with extended request context. Applied DTO design, dependency injection, and unit testing to ensure maintainability and reliability. On the frontend, improved the payment failure experience by introducing bilingual messaging and centralized customer support information, leveraging constants management and localization. The work emphasized code reuse, clear user guidance, and robust integration for downstream systems.
