- In respect to the sensitivity of my NSA work, during my time as a system administrator, I managed user access by creating and modifying user accounts, assigning roles, and maintaining group memberships in accordance with agency policies and security protocols. Tailored to ensure ongoing user compliance with system access requirements, performing periodic audits to verify permissions aligned with role-based access control (RBAC) standards.

Accomplishments:

• Streamlined user access provisioning by automating group assignments based on role, reducing provisioning time by 40%, and increasing the accuracy of access control.
• Maintained 100% account compliance by implementing rigorous auditing practices and enforcing security policies for user access, reducing account lockouts, and unauthorized access incidents.
• Managed privileged access for over 100 users across multiple secure environments, ensuring strict adherence to NSA compliance protocols.
• Led the implementation of Role-Based Access Control (RBAC) standards across classified and unclassified systems, enhancing least-privilege enforcement, and reducing redundant access by 70%.
• Collaborated with audit teams to ensure system access policies aligned with federal standards (NIST, DoD STIG), contributing to successful annual security assessments.
• Reduced audit findings related to access controls by 85% through continuous monitoring.

- Executed comprehensive data center cleanups and network modernizations to ensure optimal performance and security. Identified and resolved network vulnerabilities, established redundancy to maintain high uptime, and supported large-scale operations by managing and securing critical data assets.

Accomplishments:

• Managed a $10 billion Air Force network with an Active Directory database, utilizing the LDAP protocol to deliver secure, reliable core services to 900,000 global users.
• Administered an Active Directory environment, managing user accounts, security groups, and organizational units for over 3,000 users across multiple domains.
• Authored SOPs for hard drive installations, standardizing hardware for 32 servers across 13 sites, and ensuring consistent performance.
• Supported and implemented NetApp in an existing environment of Linux and Windows servers.
• Administrated, created, and modified DNS records, DHCP scope and reservation, troubleshot DHCP and DNS, and managed user and service accounts.
• Directly supported a 3-star general and staff during critical operations, including the Chinese surveillance balloon incident over Alaska, ensuring 24/7 communications.

- Provided IT L1 and L2 support for an aerospace operations center in Anchorage, Alaska, and managed complex network and security issues to ensure seamless and secure operations. My work involved advanced troubleshooting, implementing IT solutions, and conducting root cause analysis to maintain critical systems. I supported key ISR (Intelligence, Surveillance, and Reconnaissance) capabilities, enhancing the reliability and efficiency of joint operations between the U.S. and international allies

Accomplishments:

• Performed administrative configurations and upgrades on the master image for a 3,000-device VDI zero-client infrastructure through VCenter.
• Led a successful Windows 10 migration across 500 systems, ensuring compliance with DoD mandates, with zero operational impact.
• Displayed leadership skills by resolving four vital C2 systems, and provided pivotal support for C4ISR operations monitoring an unidentified aerial phenomenon over the course of 96 hours.
• Applied 115 patches across 20 systems, creating 746 training tasks, eliminating 20 critical vulnerabilities, and 500 risk vectors using PowerShell scripts with automated patch management tools.
