I am an experienced and results-driven IT systems administrator with a strong background in network troubleshooting, server management, and security.

I consistently resolve logged calls, configure and maintain Windows Server, Linux and workstation environments, manage LAN/WAN/wireless infrastructures, and implement security, backup and disaster recovery strategies.
