What I'm looking for

I seek a remote support role where I can leverage Office 365 and Azure AD expertise, mentor teams, and improve uptime and security.

I am a results-driven IT professional with over a decade of experience delivering remote IT support, specializing in Office 365 administration, Azure AD management, endpoint security, and complex technical troubleshooting via phone, email, and remote tools such as N-Sight and TeamViewer. I have repeatedly reduced downtime and recurring issues through root cause analysis, automation of processes, and hands-on remediation across large device estates.

As a team lead and senior support engineer I managed projects, trained junior staff, and administered Microsoft Exchange, Active Directory, and cloud infrastructure at scale — securing 2,000+ endpoints and resolving thousands of Office 365 incidents while improving operational efficiency and customer satisfaction.
