What I'm looking for

I want to continue building enterprise network security—Zero Trust, DMZ/NGFW, and multi-cloud firewall enforcement—using automation (Terraform/Ansible) and SIEM-driven threat hunting, while leading migrations, audits against CIS benchmarks, and mentoring security engineers.

I’m a Network Security Engineer with 11+ years of progressive experience designing, deploying, and managing enterprise-grade network security infrastructure across government, aerospace, and consulting. I build DMZ environments and architect Zero Trust frameworks, integrating next-generation firewall capabilities like IDS/IPS, threat prevention, URL filtering, App-ID, and WildFire across hybrid and multi-cloud environments.

In my current role, I spearheaded DMZ deployments across 5+ enterprise environments, reducing exposure by 40%, and designed AWS cloud security with Gateway Load Balancer (GWLB), VPC, Transit Gateway, and Direct Connect. I also lead large-scale Palo Alto migrations, automate provisioning with Terraform/Ansible/Python/PowerShell, enforce CIS Benchmark-aligned compliance, integrate Panorama with SIEM for threat detection, and mentor engineers to improve delivery and reduce escalations.
