You don’t need basic IT support. You need someone who understands how business infrastructure actually works. I’m a Systems Analyst with over 10 years of experience operating inside a multi-client MSP environment, managing Microsoft 365 tenants, Exchange Online, Entra ID (Azure AD), and Windows infrastructures across multiple organizations simultaneously. I specialize in: • Microsoft 365 administration (multi-tenant environments) • Exchange Online mail flow troubleshooting (NDRs, SMTP relay, forwarding restrictions) • Conditional Access, MFA, and security hardening • Azure AD / Entra ID account lifecycle management • PowerShell automation • Windows 10/11 endpoint management via RMM • VPN & firewall troubleshooting (SonicWall) • Active Directory & hybrid environments I have supported 10+ client environments at the same time while maintaining SLA-driven performance and executive-level communication. If you’re running an MSP, managing multiple tenants, or struggling with complex Microsoft 365 issues, I can step in and stabilize your environment quickly. I don’t just close tickets, I solve root causes.
