    I am a professional US based systems admin located in the Chattanooga, TN area, I have been involved in servers, hosting and server administration over 10 years now. I got my start in the security and hacking industry and went from there I have ran and help run various successful hosting businesses and as well support companies. The last few years I have been mainly doing freelance work. I an good at what I do and I love doing it. I live, eat and breath servers and would not be happy in any other type of work or industry, At this time I would be considered a level 3 systems admin, I can do anything a systems engineer can besides perl and other coding. I can do bash and shell scripting but I do not consider that programming. Anything that can be done remotely or on site I can do. I never give up and do not quit until the job is done., Also when you hire me you can expect the job to get done right the first time without fiascos and ticket tag. I also never apply for a job that I have the slightest doubt I would have trouble doing. All my work is guaranteed, If I do something and have to come back and fix something I will do so off the clock. This is a guarantee I extend to all clients and all jobs whether one time or hourly. I like to work with all my clients one on one via skype, phone or whatever communication medium you choose to use. I make sure you fully understand what is taking place and what if any follow ups are required in the future. When you hire me you get quality work, integrity and honesty, nothing less. This is my first time doing odesk so if you need I can provide many reputable professional and personal references. You get what you pay for and when you hire me you get nothing but the best quality work at reasonable rates. Why waste time going through various admins who apply to the jobs expecting to wing it with google when you have a top notch admin like me who can roll up his sleeves and jump right in to get the job done right? So choose me as your admin or IT professional, you will not regret it. My skillsets are also much more broad than allowed to be posted here. I can work with any and all control panels, operating systems, datacenters, cloud environments such as ec2, digital ocean, rackspace, etc; I also can provide consultations for network and infrastructure planning. You will not find a better admin and IT pro for the reasonable rates I charge. All work guaranteed no matter how we do hourly or one time, if you are not happy you do not pay, simple as that. Choose a pro US admin like me today and get work done instead of having to deal with the usual fiascoes involved in interviewing and trying out freelancers.  less
