In my current role as Information Technology Senior Leader at Civil Affairs Brigade Headquarters, U.S. Army, I oversee identity and access management technologies including Active Directory, PKI, and RSA SSO. I support secure hybrid cloud environments across Azure, AWS, and Cloud Platforms.

At USCYBERCOM ARE, U.S. Army, I supported enterprise systems administration and cybersecurity platforms in joint-force training environments. I also developed technical documentation, procedural guidance, and architectural artifacts to improve knowledge transfer and operational resilience.

During my Kuwait deployment with 335th Theater Signal Command, U.S. Army, I directed enterprise modernization initiatives and administered cloud-based IAM governance. My work included secure access controls, cloud resource optimization, and risk assessments.

Across roles with INSCOM / DynCorp International, Personnel Recovery Command and Control (PRC2), EUCOM JAC, U.S. Army, and Secure-24, I supported mission-critical infrastructure, incident response, and cybersecurity compliance. I’ve also used PowerShell and Command Line Code automation to improve operational efficiency and strengthen security controls.
