    Linux scripting and Administration

    United States - Last active: 12/03/2014 - Tests: 7

    From missile defense systems (AMDWS) to simple LAMP driven web applications for over 10 years I have been working in the Open Source arena with a focus on Linux Systems and some Unix Based Systems (Solaris 10, FreeBSD). I have packaged for multiple Linux distributions, primarily RPM based, but do have some deb experience. For a brief period of time I ran my own Linux Distribution (Synergy Linux) to make in house servers easier to strip down and maintain for various pin point tasks (ie. NTP servers etc.) I am familiar with mock, koji and other Redhat distribution based imaging systems. I have had to edit and write with multiple scripting languages, bash, ruby (selenium), python, perl and even modified C and C++ patches to apply cleanly to new packages. I like a good challenge and to continue pushing myself to learn something new. I currently am working for a great employer as a Linux and Cisco Unified Call Manager Administrator, but I am in what I like to call maintenance mode. So I am looking for challenging side jobs to do in order to keep me on the cutting edge of opensource technologies. Also I don't mind doing remedial jobs just to earn a few extra dollars to further support my family. Depending on what other jobs I am currently doing I may be looking for a Linux support role, or just simply a data entry role I can write a script for. In either scenario I am excited to network and meet new people. Thank you for your consideration (and time in reading this). Kind Regards, Jeremiah
