Vivek Aggarwal developed a public register extension for the DEFRA/epr-data-sqldb repository, focusing on supporting both small and large producers within the extended producer responsibility framework. He designed and implemented new database schemas and stored procedures using SQL, enhancing data management and reporting capabilities. By integrating these changes into the RegistrationJourney, Vivek enabled unified data flows and improved readiness for regulatory compliance. His work addressed the need for scalable, auditable reporting by strengthening the underlying data handling processes. Over the month, he demonstrated depth in database development and data reporting, delivering a foundational feature without addressing bug fixes.
