Thamil Selvan

I’m an IT Support & System Administration professional with hands-on experience in Windows systems, Microsoft 365 administration, Azure fundamentals, and day-to-day infrastructure support. I handle user management, access control, hardware/software troubleshooting, and ticket-based operations with a clear focus on minimizing downtime.

I’ve worked across environments involving Active Directory, O365, basic Azure cloud resources, and standard networking components like switches, routers, VPN, and firewalls. I’m comfortable resolving incidents, managing requests, documenting fixes, and improving the overall IT workflow.

Committed to continuous learning — recently completed and certified in Microsoft Azure AZ-104, with practical experience in VMs, storage, RBAC, backup, and monitoring labs. I’m actively aiming to grow into a full cloud/system support role.
