I have been working in internet support and network operations since 1997. My practical work experience includes: 

Connectivity: channelized DS3, T1 and DS0 customer premise equipment setup for installation (using Cisco routers and a variety of CSU/DSU's), bringing live of point-to-point and frame relay T1/DS0 circuits.  

Servers: configuration of hardened production White Box Linux and RedHat Linux servers (named, syslogd, traffic monitoring (mrtg), sendmail with spam filtering, OpenVPN, etc). 

Security: abuse administration, DOS attack handling (both inbound and outbound), network security design and implementation (using network and server analysis, Cisco access-list programming, RedHat IPTables  firewalling, filesystem database, remote syslog, etc). 

Network engineering: BGP configuration and load balancing for Tier2 and Tier3 networks, peering administration for a Tier1 and several Tier2 networks, occasional large circuit setup (DS3 - OC3), WAN engineering using OSPF, EIGRP and BGP.

Support: Diagnosis and resolution of T1, DS0, and cable modem internet connectivity problems, DNS help (problem solving regardless of the platform, configuration repair on Linux platforms, and registrar issues), LAN troubleshooting, mail delivery (smtp) problem solving (including both DNS MX record issues and identification of mail server problems), routing fixes (nonrouting IP blocks, routing loops). 

I specialize in Cisco router and RedHat/Whitebox Linux solutions for businesses and ISP's. Currently, most of my work is done remotely, without requiring a site visit.
