System Administrator delivering secure, reliable Windows and network operations.
NigeriaWhat I'm looking for
I’m a results-driven IT professional focused on System Administration, Network Support, and IT Helpdesk. I manage secure and reliable IT operations by combining Windows Server expertise with strong Active Directory and Microsoft 365 administration.
Currently, I install, configure, and maintain Windows Server 2016/2019/2022, administer Active Directory (DNS, DHCP, Group Policy, and file/print servers), and support Microsoft 365 through Exchange Online, Teams, SharePoint, OneDrive, and Intune. I also handle user accounts, permissions, and access control across AD/Azure AD, and provide 2nd and 3rd level technical support with escalation resolution.
Previously, I supported desktops, laptops, printers, Windows 10/11 deployments, and end-user troubleshooting through helpdesk ticketing. I also delivered network support across LAN/WAN/Wi‑Fi—installing and configuring switches, routers, firewalls, access points, and handling VPN and connectivity issues—while documenting procedures and ensuring uptime through proactive maintenance.
