In December 2025, Nicolae Negru enhanced the DEFRA/epr-common-data-api repository by implementing Organization Registration Journey Tracking. He introduced a new RegistrationJourney column to the submissions table and updated related database views, enabling more granular analytics and reporting of the organization onboarding process. Using SQL and applying data modeling and database design skills, Nicolae delivered an end-to-end schema change that improved data visibility for business decision-making. The work focused on backend data model enhancements rather than bug fixes, demonstrating depth in technical execution and a clear understanding of analytics requirements within the context of a production data API environment.
