About

I’m a retired U.S. Army professional with over 20 years of experience in IT operations, network management, and electromagnetic spectrum systems. I hold a Master of Science in Digital Forensics and Cyber Investigation and a Bachelor of Science in Cybersecurity Technology from the University of Maryland Global Campus. I’m also certified in CompTIA Security+, Cisco Certified Network Associate (CCNA), and Certified Ethical Hacker (CEH).

Over the course of my career, I’ve provided technical support, network troubleshooting, and system administration across both classified (SIPRNET) and unclassified (NIPRNET) environments. I’ve managed and configured network devices, implemented cybersecurity best practices, and supported mission-critical operations for joint and coalition forces.

My achievements include developing and leading training programs for service members, managing complex RF and IT systems, and providing reliable Tier I and II technical support in high-demand environments. I take pride in being detail-oriented, dependable, and committed to maintaining operational excellence through secure and efficient IT practices
