Administer SharePoint Online and SP2013 environments — provisioning site collections, managing libraries, lists, content types, and subsites for enterprise clients across Microsoft 365 tenants. Manage permissions and access governance using SharePoint groups and Azure Active Directory — enforcing least-privilege principles and maintaining security compliance standards. Use PowerShell scripting for SharePoint administration tasks including bulk permission changes, site provisioning automation, and health checks via PnP PowerShell and SharePoint Online Management Shell. Operate SharePoint Admin Center for tenant-level configuration — managing storage quotas, external sharing policies, service health monitoring, and audit log reviews. Provision and configure new SharePoint sites for business teams — gathering requirements, setting up structure, applying templates, and handing off with user training. Provide end-user support for SharePoint access issues, permission errors, and collaboration queries — resolving tickets and maintaining smooth day-to-day operations. Completed 7–8 months of enterprise training in Azure, AWS, and Microsoft 365 technologies prior to production deployment at Tech Mahindra.
