    Linux Administrator

    United States - Last active: 12/23/2014 - Tests: 7

    -- Red Hat Certified -- Beginning with Ubuntu in 2008, I now manage CentOS servers for LogicDudes.com, my local tech support company. I have a wide range of experience including setting up headless KVM virtual hosts, configuring Nginx and Apache with Mod Pagespeed, encrypting filesystems and network traffic, monitoring system performance with Nagios, troubleshooting selinux complications, and automating common tasks with scripts. I am certified by Red Hat and stay up to date with the latest methods and services. I do my best to make sure all of my systems run at their best and are as secure as possible. My favorite thing about Linux is that anything is possible and everything is free, somebody has probably done it before and documented everything. -- Script Writer -- At the end of the day, everything is about text manipulation. I write scripts in bash, php and perl to automate tasks and work with websites. Everything from scapers to emailers to automated submitters, I can create custom scripts to automate any process. My scripts are great because they are created to do one process and to do it well. They are also properly documented so future updates are quick and easy.
