    Over 4 years experience in the design, installation, configuration, and troubleshooting of networks and their associated components.Over two years experience working with different Server environments, including mostly Windows, but also Linux and Mac. While my primary focus and training has been Cisco and Windows Server centric, I have an interest in most forms information systems. I've used and/or administered a very wide variety of devices and software I pretty much live and breathe computer networking; it comes naturally to me and always has, I really enjoy the work I do and do my best to provide the highest quality of service that I can to my clients. I am mostly seeking opportunities to utilize my networking or server administration skills for you or your business. -------------------------------------------------------------- I am also a writer, and have written hundreds of short stories and a few articles. I am also looking to expand my repertoire as a writer as well, and am also available to ghost write and write articles as well. I focus on a wide variety of genre's, but my forte is science-fiction, fantasy, or romance. I am willing to write in any genre if the concept is intriguing enough.  less

    LinkedIn http://www.linkedin.com/in/jmdots Summary I've worked in technical administration, technical support, customer service or leadership roles for all but a few months of my adult life. In this time, I climbed the ranks of a highly-modern, lightning-paced, large-scale, multi-OS supercomputing environment in Area B of Wright-Patterson Air Force Base (WPAFB) and became an avid user of all things open source. The place which was my professional home of over six years is known as the “Air Force Research Laboratory DoD Supercomputing Resource Center” or "AFRL DSRC" for short. The AFRL DSRC environment is home to the #19 supercomputer on the June 2011 Top500 Supercomputer List, a mammoth computer for which I received training: Cray Inc.'s "Raptor" XE6.
