At Cognizant Technology Solutions, I administer six Microsoft 365 workloads for more than 22,000 employees, including Exchange Online, SharePoint, Teams, OneDrive, M365 Apps, and Service Health. I resolve high-priority incidents, automate recurring administration with PowerShell, and investigate compliance requirements through Purview Content Search, audit logs, and PST operations.

Previously at TEKsystems India, I protected enterprise Microsoft 365 tenants against phishing, spoofing, malware, and impersonation, delivering over 95% CSAT. I handled critical MDO and EOP escalations, implemented SPF, DKIM, DMARC, and ARC, and configured anti-phishing, anti-malware, Safe Links, and Safe Attachments policies.

At Tocumulus Technology Solutions, I led Microsoft 365 migrations, managed identity and security controls including Entra ID, Conditional Access, MFA, PIM, DLP, and MIP/AIP, and supported customers through cutover and stabilization.
