Worked on the DEFRA/epr-data-sqldb repository to deliver a feature extending the public register to include both small and large producers, enhancing coverage for extended producer responsibility data. Designed and implemented new database schemas and stored procedures using SQL, focusing on robust data management and reporting capabilities. Integrated these changes into the RegistrationJourney, enabling unified data flows and supporting regulatory compliance requirements. The work emphasized scalable and auditable reporting by improving data handling processes within the database. No bugs were addressed during this period, with efforts concentrated on building foundational infrastructure for future enhancements in data processing and regulatory readiness.
