Vladimir Orekhov

Network Administrator with nearly a decade of hands-on experience running enterprise infrastructure for a Minnesota county government — networks, servers, security, web, and the homelab that quietly became a small datacenter. Track record of finishing migrations cleanly, hardening what's there, and shipping side projects in PHP, Python, and JavaScript on the side.
