    Network Security Engineer

    United States - Last active: 14 days ago - Tests: 10

    Need web scraping? Perl programming? Data parsing? Quick turn-around times. Accurate estimates on time and turn-around times? Abilitiy for someone to be honest if they don't feel it's a fit to save both of us the time and aggrivation if we aren't? Need someone to care about the work they provide. I do a LOT of custom, per order scripting and provide all the scripts when done so you can run them again the future, especially with web scraping. I like giving a "fixed cost" estimate so we know exactly what it will cost you and I will give you an accurate turn-around time. I will often under promise and over deliver on my delivery times just to make sure I do not disappoint. Willing to negotiate fees. I may not be the cheapest, but i am VERY fair, and again, care about the service I will provide for you. My evenings are usually very open so I have the time to dedicate to your project and often will finish them within the first 48-60 hours of receiving the details of the project. (if not sooner) From the time I can remember, I have been working with computers. It all started with an Apple //e and prodos 3.0. Then I got my first MSDOS PC and began programming in GWBasic then Qbasic. By the time I was 12, I had a few computers running OS2 warp. From there I started and maintained a free 4 line BBS for a few years at the age of 13. I currently work at Trustwave as a Network Security Engineer. The tasks i perform here vary from troubleshooting and maintaining various Trustwave branded firewalls as well as Cisco ASAs, Junipers, Proventias, Fortinets, and Sonicwalls to scripting programs to perform mass changes to various devices. Other tasks include working with point to point ipsec and openvpn VPN connections, traffic inspection, routing, iptables, database administration, two factor authentication implementation, post mortem forensics on failed/failong devices. This is a rewarding position that keeps me excited about going to work daily. I plan to be here for a long time! I worked for Sol Tec / Riverwatcherfor about 14 years. I started out as the Network Administrator at the Bensenville branch. I had no idea what BGP routing or NAT was at first. After a couple years there, I moved to the corporate office in Champaign, IL to be their Senior Network Administrator. Since then, our company has gone through some major changes and now I have taken on the role of Network and Systems Admin. I have managed to pick up a lot of knowledge working for our fast based, leading edge company. I have always been interested in computer security and the use of problem solving and linear thinking to produce solid solutions. I then began to build "smart" software that would perform many of the maintenance tasks I found myself doing on a regular basis. This software is used to help me monitor and maintain our server cluster and gets "smarter" every day. We currently have a GREAT team and I am confident we will continue to provide cutting edge solutions for our various clientele.

    Professional Systems Admnistrator

    United States - Last active: 2 days ago - Tests: 3

    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.
