    Network Security Engineer

    United States - Last active: 15 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.
