Worked on the DEFRA/epr-prn-integration-function repository to enhance data fidelity in organization and trading entity representation within backend services. Developed support for an OrgName parameter in the recipient service stub, ensuring that organization names remain distinct from trading names throughout the integration flow. This update, implemented using C# and RESTful service principles, aimed to improve downstream processing accuracy and reduce the risk of misattribution. Unit tests were updated to validate the separation of these fields, with all changes documented through traceable commits. The work demonstrated a focused approach to backend development and robust unit testing within a short project period.
