What I'm looking for

I’m looking for a role where I can own IAM operations and access lifecycle management, troubleshoot escalations, and deliver secure, audit-ready RBAC with excellent customer service in a fast-paced, ITIL-aligned environment.

Results-driven IT Support and Identity & Access Management professional with extensive experience supporting enterprise environments in cybersecurity, IAM operations, and service desk leadership. I bring hands-on expertise in Active Directory, Microsoft 365, SailPoint, Okta, and Microsoft Entra ID (Azure AD), with a strong focus on access lifecycle management and policy-compliant access solutions.

In my recent role as a Cyber Security Consultant – Identity & Access Management / Business Analyst at EY GDS, I managed identity and access lifecycle processes, implemented role-based access control (RBAC), and supported onboarding, transfers, and termination for enterprise users. I resolve IAM-related incidents, handle escalations, and support audit activities through access reviews—backed by troubleshooting, incident resolution, and ITIL-aligned service quality across global teams.
