What I'm looking for

I'm seeking opportunities where I can lead RMF, ATO, continuous monitoring, vulnerability management, and security compliance efforts for federal or DoD systems.

I've supported the U.S. Secret Service through TRIA Tech and Zermount, leading RMF and SA&A activities to maintain ATOs for federal information systems.

I develop SSPs, risk assessments, POA&Ms, system boundaries, and accreditation artifacts while implementing NIST 800-53 controls through RSA Archer, Xacta, and eMASS.

Across Chickasaw Industries, Southern Research, NIKSOFT, IndraSoft, and DISA, I've led security testing, STIG compliance, vulnerability management, contingency plan testing, and continuous monitoring for classified and unclassified environments.

I've also managed enterprise server security, Active Directory, patching, incident response, personnel security processing, classified document accountability, and security briefings. I hold an active CompTIA Security+ certification and Active Top-Secret Clearance.
