What I'm looking for

I am looking for a role in a dynamic organization that values innovation and offers opportunities for professional growth in cybersecurity.

With over a decade of hands-on experience in cybersecurity, systems administration, and federal IT operations, my journey began in 2014 as a U.S. Army IT Specialist. I have a proven track record of securing complex networks, managing Microsoft and VMware infrastructures, and supporting mission-critical systems across global environments. As a Security+ certified professional, I have experience implementing STIG compliance, Active Directory security, Intune device management, and PKI.

Currently, I am expanding my cloud security expertise with Azure-focused training. My military background has equipped me with technical knowledge, leadership skills, adaptability, and a clear focus on delivering reliable, secure IT solutions. I am eager to contribute my skills to a forward-thinking organization where I can continue growing and making an impact.
