During May 2025, Kafai focused on backend feature development for the sequinstream/sequin and supabase/pg_graphql repositories. He enhanced authentication flows in Elixir and Phoenix by enabling customizable redirect options for unauthenticated users, supporting smoother onboarding scenarios. In Rust and SQL, he introduced a per-table max_rows directive for supabase/pg_graphql, allowing granular data governance and performance controls by prioritizing table-specific limits over global defaults. His approach emphasized maintainability, with comprehensive tests covering both tables and nested views, and a refactored builder to ensure predictable query limits. The work demonstrated depth in API development, authentication, and database management without major bug reports.
