What I'm looking for

I seek a hands-on IT support role in a security-conscious organization where I can manage servers/networks, mentor teams, improve uptime, and advance in systems or network administration.

I am an accomplished IT professional with over a decade of hands-on experience providing technical support, system administration, and network operations in high-security and government environments.

My background includes maintaining Windows Server environments (2003, 2008 R2, 2012 R2), Active Directory, DNS, DHCP, VERITAS Backup Exec, Remedy ticketing, and DOD-approved communications software while meeting strict security protocols.

I lead teams, drove process improvements, reduced downtime through preventive maintenance, and built documentation and training resources to improve service delivery and operational reliability.
