Albuquerque, New Mexico, United States

I handle routine maintenance, troubleshoot issues, and ensure strict adherence to security protocols. Establishing servers (RHEL 7 and 8), deploying software using tools like Ansible and Docker, and creating comprehensive documentation for other teams are integral aspects of my responsibilities. My expertise spans Linux systems administration, secure system engineering practices, and security best practices. I am proficient in Docker, Kubernetes, Ansible, PostgreSQL, SonarQube, virtual machines, Python coding, and cloud infrastructure.

As a cybersecurity professional, I’ve successfully developed critical documentation, including Plan of Action and Milestones (POA&M) and System Security Plan (SSP), ensuring Authority to Operate (ATO) certification across 29 different Xacta packages. My expertise extends to conducting thorough wireless network sweeps, remediating rogue access points, and bolstering network security. Additionally, I revitalized the Assured Compliance Assessment Solution (ACAS) server, performed credentialed scans, and maintained ATO accreditation for 12 DoD Weapon Systems. My innovative approach includes automating routine tasks, resulting in a remarkable 36-hour annual time savings. Furthermore, I’ve developed site-level Incident Response Tactics Techniques and Procedures (TTPs) and pioneered a custom PowerShell script for efficient incident identification, leading to a significant 40-hour labor reduction per quarter.

As a systems administrator, I successfully managed the Domain Controller server, overseeing critical services such as Domain Name System (DNS) and Active Directory Domain Services. My expertise extends to developing PowerShell scripts that enhance the capability to operate and maintain over 700 site computers, user accounts, and groups within Active Directory. Additionally, I performed neccessary equipment lifecycle management, ensuring proper identification, assessment, and disposition of legacy hardware reducing attack surface. My commitment to security extends to maintaining compliance with Joint Special Access Program Implementation Guides (JSIG). I’ve also instituted robust system security policies and standardization across multiple domains. Furthermore, I’ve performed system hardening using Security Technical Implementation Guides (STIGs) and Security Content Automation Protocol (SCAP). Lastly, my vigilance in managing port security and MAC address filtering prevents rogue devices from infiltrating the network.
