At Argentum IT, I support client endpoint, network, identity, and infrastructure systems in a managed-services environment. I troubleshoot issues across firewalls, routing and switching, DNS/DHCP, wireless connectivity, and endpoints, and participate in CMMC-related technical-control review and remediation planning.
With the Army National Guard, I support classified and unclassified systems and maintain authorization and security documentation under DoD RMF and STIG requirements. I also review logs and security indicators and support continuous monitoring.
I independently identified CVE-2025-63560 in a Kiloview E3 device, validated the impact, and coordinated disclosure with the vendor through remediation. I earned the Hack The Box Certified Penetration Testing Specialist certification through a hands-on enterprise penetration test and technical report.
In my Active Directory provisioning homelab, I built a Windows Server 2025 AD DS/DNS environment with a provisioning path connecting a Node.js/Express web form, PostgreSQL, a REST API, and PowerShell New-ADUser automation. I verified domain authentication with the provisioned account.
