Systems Administrator & Help Desk Administrator

Hey, I'm Sean.
I build reliable, secure, human-friendly systems.

I keep cloud environments tidy, endpoints compliant, and people happy. Mortgage-industry experience, Microsoft-first stack (Azure, M365, Intune), and a healthy respect for security and UX.

About

I'm a Systems Administrator focused on Microsoft cloud: Azure, M365, Intune, and identity. I translate business goals into simple, secure technical outcomes. In the mortgage world, compliance and uptime matter — I build guardrails so teams can move fast without breaking things.

🔒 Security-driven: baseline hardening, least-privilege, incident basics
☁️ Cloud-first: Azure AD/Entra ID, Conditional Access, PIM, device compliance
🧰 Automation: PowerShell, policy-as-code vibes, tidy documentation
🤝 Human UX: clear runbooks, lightweight training, no heroics required
