I resolve Microsoft 365, Windows, server, network, and customer support issues across enterprise environments.
NigeriaWhat I'm looking for
I've supported Microsoft through Upwork since 2020, resolving Windows and Microsoft 365 issues for customers through phone, chat, and ticketing support. I processed more than 3,000 technical support requests in three months while following issues through to resolution.
I troubleshoot and maintain Windows servers, workstations, Active Directory, Microsoft 365, Exchange Online, Azure Active Directory, SharePoint, OneDrive, Teams, MS SQL Server, and mobile devices. I also perform remote installations, Windows 10 upgrades, server migrations, and configuration work using Kaseya.
My infrastructure support includes SonicWall, Cisco, Netgear, firewalls, network switches, VLANs, VMware, Citrix, DaaS, SaaS, and IaaS environments. I've held technical support and network roles at TEK Expert, Sterling Bank, Citi Investment Capital, and South Atlantic Petroleum.
I'm a Microsoft Certified Trainer and hold renewed Microsoft 365 administration, security, mobility, identity, and Teams administration certifications. I also use AI tools including Copilot, ChatGPT, and Gemini to support effective technical work.
