Over a two-month period, this developer delivered seven new features across DEFRA/epr-frontend-accountmanagement-microservice and DEFRA/epr-regulator-service, focusing on regulatory UI enhancements and security hardening. They implemented Content Security Policy directives to strengthen resource restrictions, introduced feature-flagged Razor Pages for managing registrations, and built new interfaces for handling reprocessing details and waste licenses. Their work included backend session management, navigation improvements, and integration of C# service layers with AutoMapper for model mapping. By developing end-to-end solutions in C#, HTML, and Razor, they improved regulatory data capture, authorization visibility, and risk controls, while maintaining robust unit testing and exception handling practices.
