During September 2025, Magbanu developed a scalable database migration framework for user authentication in the jeffreywallphd/AutoProphet repository. Focusing on backend development and database management, he introduced a MigrationManager class and accompanying SQL scripts to enable safe, incremental schema changes with clear rollback paths. The work included adding new authentication fields such as PIN, last_login, and account_creation_date, as well as implementing a dedicated migration for PIN encryption and enforcing field nullability to enhance security and data integrity. Using Node.js and SQL, Magbanu laid a robust foundation for ongoing evolution of the authentication subsystem with minimal downtime.
