Waleed Zahedi enhanced organization membership management for directory-backed customers in the workos/workos-python and workos/workos-node repositories. He introduced a directory-managed flag to the OrganizationMembership model in both Python and TypeScript SDKs, aligning data contracts and terminology across languages. His approach included updating test mocks and improving unit test coverage to ensure production fidelity and robust contract evolution. By focusing on API development, backend logic, and user management, Waleed reduced integration gaps and streamlined customer onboarding. The work demonstrated thoughtful cross-repo consistency and careful attention to type safety, reflecting a solid understanding of backend development and multi-language SDK maintenance.
