What I'm looking for

I’m looking to advance in network and security operations where I can lead threat detection, SIEM-driven incident response, and vulnerability management—protecting high-impact infrastructure while expanding my expertise in cloud security and automation.

I’m a Network Security Engineer with a strong Computer Science foundation and hands-on experience securing government, defense, and enterprise environments. I’ve built expertise in network architecture defense, firewall administration, IDS/IPS, VPN, and vulnerability management, and I bring operational discipline to security operations and incident response.

Currently, I serve as Cyber Officer II at the Defense Space Administration, where I lead threat detection operations, maintain network integrity, enforce security protocols for critical national infrastructure, and coordinate incident response with cross-functional teams. I deploy and manage SIEM solutions, conduct threat intelligence analysis, and monitor network traffic for anomalies, while using Python scripting and traffic analysis to support automated log analysis and faster decision-making; previously, I also administered high-availability SQL databases (99.9% uptime) and achieved 100% compliance in web security testing before release.
