    Over my 15+ year career, I have a very broad range of IT and Telco experience. American Citizen, English as only language. I have wide experience in TCP/IP nework design, planning, implementation and support. Experience specifically with Routing (RIP, OSPF, EIGRP, etc.), Switching (VLAN), and Security (Firewall and VPN) on the network side. VoIP experience with setting up full PBX functionality with Trixbox (Asterisk on CentOS with FreePBX), or Asterisk stand-alone with anywhere from 5 to 500 end users including remote users, and installing and helping to implement Avaya IPOffice (small office VoIP solution) and 8500/8700 (Enterprise level VoIP) for 10 to 2500 users. I have consistently increased my knowledge over the years to include everything from simple web page design and updates, to desktop and server build and repair, and mostly including network connectivity from the desktop all the way to Internet and VPN connectivity. I try to continually keep up with new technology and am very open to testing and learning anything new.
