Nick Posey

As a versatile and solutions-driven IT professional, I bring extensive experience across systems engineering, infrastructure support, and application development. My technical expertise spans .NET development, Active Directory management, cloud platforms like AWS and Azure, and secure VPN architecture. I have a solid background in both hardware and software systems, including configuring firewalls, routers, switches, and WiFi networks, managing RAID storage, and maintaining enterprise-level Microsoft Exchange and SQL-based systems. I’m proficient in virtualization technologies such as Hyper-V and VMWare, as well as scripting and automation with PowerShell. With practical knowledge of Linux environments and a strong grasp of core networking protocols (TCP/IP, DNS, DHCP), I’m adept at supporting and optimizing complex, hybrid IT infrastructures.
