• Manage and troubleshoot infrastructure technologies including WAN/LAN, TCP/IP, DHCP, DNS, VPN, and Active Directory.
• Deploy, configure, and support operating systems including Windows, macOS, and Linux (Ubuntu, CentOS, RHEL).
• Validate and troubleshoot Group Policy Object (GPO) Resultant Set of Policy (RSoP) and JAMF configuration profiles on endpoints.
• Manage user account lifecycle: creation, modification, deactivation, permissions, and directory maintenance (e.g., Active Directory).

• Configure, deploy, and support mobile devices (Apple iOS and Android) across enterprise environments using Mobile Device Management (MDM) solutions.
• Support single- and multi-site videoconferencing solutions and advanced conference room control systems (Cisco experience is a plus).
