What I'm looking for

I'm seeking permanent, full-time, or contract roles to secure and optimize DoD/Government networks, mentor teams, and apply my TS/SCI clearance and 12+ years' experience.

I am a Systems and Network Engineer with over 12 years of experience delivering secure, reliable communications for DoD and government customers. I hold an active TS/SCI clearance with CI Poly and apply practical solutions across network design, monitoring, and incident response.

I've detected and mitigated vulnerabilities using tools such as Splunk, Tanium, Tenable, Wireshark and Nmap, led systems integration efforts, and mentored junior engineers while producing documentation and dashboards to improve operational posture. I am seeking permanent, full-time, or contract roles where I can apply my certifications and hands-on experience to harden and optimize mission-critical networks.
