Worked on user management enhancements for the supabase/supabase-py repository, focusing on strengthening authentication flows and supporting single sign-on users. Developed and delivered a targeted feature that extended the User model by adding fields to track SSO status, account deletion, and ban periods, directly addressing gaps in authentication reliability and user lifecycle governance. The implementation involved updating Python ORM entities and aligning backend data modeling with evolving authentication requirements. Leveraging skills in API development and backend engineering, this work established a foundation for broader SSO support and policy-driven user management, reducing risk in production authentication flows and enabling future enhancements.
