At First Brands Group, I resolved complex hybrid identity issues across a distributed environment, including an Azure AD Connect sync failure caused by duplicate attributes. I corrected the conflicts, validated a targeted delta sync, and implemented automated duplicate-attribute detection.

At Optomi, I directed the implementation of ManageEngine ADManager Plus and configured automated identity lifecycle workflows, RBAC, and helpdesk delegation. Earlier, I supported Windows systems administration across regulated environments, including resolving domain controller replication failures and automating Windows Server deployments.
