Worked on the xataio/agent repository to enhance database security by implementing Row Level Security readiness across the public schema. Developed a SQL migration that sets default table permissions for the authenticated_user role, ensuring that RLS policies automatically apply to all current and future tables. This approach reduces the risk of misconfiguration and supports scalable, multi-tenant access control. Leveraged expertise in SQL, database management, and database security to deliver a solution that strengthens data integrity and compliance readiness. The work focused on foundational security improvements, laying the groundwork for robust access control without introducing breaking changes or manual intervention.
