Tonbaliklimakarnha developed a SCIM-based Partial User Updates feature for the better-auth/better-auth repository, focusing on integration with Microsoft Entra ID. The work centered on enabling partial updates to user resources through SCIM operations, streamlining administrative workflows and aligning with Entra ID provisioning standards. Using TypeScript and leveraging full stack and API development skills, Tonbaliklimakarnha implemented SCIM compatibility to support Microsoft Entra ID’s protocol requirements. The feature reduced manual effort for administrators by allowing targeted user updates rather than full replacements. This contribution demonstrated a focused approach to protocol compliance and efficient user management within a modern authentication system.
