What I'm looking for

I seek a technical role managing Exchange/M365 messaging infrastructure where I can lead migrations, automate operations with PowerShell/MS Graph, solve complex mail-flow issues, and improve reliability in a collaborative, process-driven environment.

I am a Senior Exchange Administrator with extensive hands-on experience managing Exchange 2016, Exchange 2019, and Exchange Online in hybrid M365 environments. I focus on end-to-end mail flow, DNS and SMTP routing, hybrid connectors, transport rules, message tracing, and mailbox migrations.

I automate repetitive operational tasks using PowerShell and Microsoft Graph, building scripts that pull email activity, integrate with SharePoint and Power BI, and run as applications for reliable reporting and management. I have implemented Conditional Access controls, supported Proofpoint and Cisco IronPort platforms, and resolved complex incidents through cross-team collaboration and Microsoft support engagement.

I deliver dependable day-to-day operations and project work including migrations, Teams–Exchange integration troubleshooting, mailbox and archive management, and knowledge-base maintenance. My certifications include CCNA, MCSE, and Exchange 2016 certification, and I bring a proven track record of improving delivery success rates and operational efficiency through automation.
