What I'm looking for

I'm looking for a cloud support role where I can troubleshoot Microsoft 365, Exchange Online, and identity issues, improve service reliability through automation and security practices, and support global teams in a high-volume SLA-driven environment.

I've supported enterprise Exchange Online environments at Tek-Experts across the US, Canada, and EMEA, resolving 20–30+ complex incidents weekly involving mail flow, mailbox access, and authentication while meeting SLA targets.

I strengthen Microsoft 365 operations through secure email migrations, SPF, DKIM, and DMARC configuration, and troubleshooting with Message Trace, Transport Rules, and Exchange Online Protection. On Upwork, I guide SMB customers through Microsoft 365 product selection, licensing, onboarding, and productivity best practices across Teams, SharePoint, and Outlook.

I've also built PowerShell automation for bulk user creation and permission assignments, reducing manual administration time by 60% and supporting consistent role-based access control.
