Work History

October 2025

15 Commits • 5 Features

Oct 1, 2025

October 2025 highlights: Delivered domain-aware and claim-based user filtering enhancements across identity governance and SCIM provisioning, added Role Management Service integration for role-based user queries, and laid groundwork for Approval API v2. All new filtering paths are covered by unit tests, and several test failures were stabilized to improve code quality. These changes improve accuracy of multi-domain user lookups, enable granular access control, and accelerate future integrations.
