During May 2025, contributed to sequinstream/sequin and supabase/pg_graphql by delivering customer-facing features focused on authentication and data governance. Developed a flexible redirect mechanism for unauthenticated users in the authentication flow, enhancing onboarding experiences. In supabase/pg_graphql, introduced a per-table max_rows directive, allowing granular control over query limits and prioritizing table-specific settings over global defaults. This work included loading configuration from the SQL context, comprehensive test coverage across tables and nested views, and a builder refactor to improve maintainability. Leveraged Elixir, SQL, and the Phoenix Framework throughout, emphasizing reliability, testability, and clear business value in backend and database development.
