Network Engineer

I'm a network engineer for an international company that provides software as a service infrastructure to emergency medical departments/organizations and disaster preparedness entities. I'm part of a small and tight-knit team that maintains network connectivity for the company's ~30 offices and datacenter presences worldwide. As a member of this team, I am exposed to a large range of infrastructure responsibilities. As such, I have gained extensive experience with Cisco equipment. I regularly work on the following platforms: Cisco ASA, Cisco ISR G2/3 Routers (IOS & IOS-XE), Cisco Nexus/Catalyst switches in remote office access and datacenter environments, and Cisco WLC/AP wireless. I have had significant exposure to network protocol standards such as: BGP, OSPF, IPSEC, DMVPN, and the following IEEE working groups: 802.1, 802.3, and 802.11. Working knowledge of Cisco technology includes: Just about everything ASA, Cisco FlexVPN, VRF-aware NAT/Routing, Cisco Nexus switching, and EIGRP. I also have fair exposure/understanding of additional Cisco networking products such as: Cisco Fabricpath, Cisco TACACS with Cisco Secure ACS, Cisco Catalyst VSS. Very recently I've been starting to explore Cisco cloud networking technologies. To say the least, I love networking and can quickly learn new protocols and hardware. In my spare time, I maintain my own private network with a mesh tinc VPN overlayed on top of the Internet, run datacenter hosted Linux servers for personal and business hosted websites/email/DNS, talk to people all over the world with amateur (ham) radio, and travel as much as possible.
