Laura Todd enhanced API reliability and contract clarity across multiple DEFRA repositories, including epr-facade-account-microservice and epr-payment-service, by aligning HTTP response codes and error handling with Swagger and OpenAPI specifications. She focused on backend development using C# and RESTful APIs, refining response semantics and standardizing return types to improve client integration and developer experience. Laura addressed inconsistencies between code and documentation, implemented precise status codes such as 204 for no-content responses, and improved Swagger documentation for accurate data structure rendering. Her work demonstrated depth in API design, code refactoring, and unit testing, resulting in more maintainable and predictable services.
