What I'm looking for

I’m looking for a role where I can own secure enterprise systems, improve uptime, and strengthen identity, endpoint, and network security—especially through automation, clear documentation, and dependable support for remote and hybrid teams.

I’m an IT System Administrator with 15+ years of experience maintaining enterprise infrastructure, security, and cloud services. I focus on dependable operations, proven uptime, and strong incident readiness across remote and hybrid environments.

I’ve administered Microsoft 365 for 500+ users and managed identity and access through Microsoft Azure AD / Azure Entra ID, including MFA and Conditional Access. I’ve also built and supported Windows Server environments running on Nutanix AHV, improving scalability and reliability.

On the security side, I lead cybersecurity awareness initiatives using KnowBe4 and Microsoft Defender, including phishing simulations and role-based training. I also triage and remediate endpoint security alerts in Microsoft Defender for Endpoint, strengthening incident response and endpoint protection.

I’m hands-on with multi-site networking and monitoring—deploying and managing Cisco Meraki infrastructure and tracking network health with tools like Auvik and Wireshark. I also use prompt engineering to automate repetitive security tasks, improve alert triage workflows, and accelerate troubleshooting and documentation.
