At Grupo CGD, I provide Tier 1 support for more than 5,000 enterprise users across Windows and Microsoft 365, administering Active Directory, Microsoft Entra ID, Exchange Online, and Intune while maintaining 95%+ SLA compliance.
I've also delivered Tier 2 support for Brazilian government clients at Hepta IT and built infrastructure experience at GetSwitch IT and Zalle IT. I troubleshoot endpoint, hardware, software, VPN, DNS, DHCP, and TCP/IP issues, deploy devices, and automate repetitive support work with PowerShell.
