What I'm looking for

I seek a Microsoft 365/IAM role focused on security, compliance, and collaboration—remote-friendly teams where I can lead migrations, optimize licensing, improve UX, and mentor junior admins.

I am an IT professional with 9 years' experience specializing in Microsoft 365 administration, Identity and Access Management, and enterprise collaboration tools. I have administered a global M365 tenant for 10,000+ users, implemented MFA and Conditional Access reducing unauthorized logins by 35%, and led a license optimization project that achieved 15% cost savings.

I create SOPs and job aids to streamline onboarding and support, provide L3 escalation for M365/IAM issues, and run migrations and compliance reporting using Power BI and Excel. I prioritize secure, scalable environments, strong user experience, and cross-team collaboration to align IAM with security frameworks.
