    Hey, thanks for checking my profile, one thing you can be sure of is that you found your WordPress/Drupal guy. In fact, I found a new love in web development with WordPress and Drupal. I face every new piece of code as a fresh new beginning, a chance to do it even better, my intensive WordPress/Drupal experience comes from 10 years of practice, training, failures and successes. I'm also a Linux power user, trust me, that helps, and I'm a JavaScript guy, a little search on Google will prove that https://www.google.com/search?q=Nabil+Kadimi.

    Jamie R.

    Reliable Software Engineer specialised in desktop software

    Spain - Last active: 19 hours ago - Tests: 8 - Portfolio: 1

    I have a degree in Computer Science B.Sc from the university of Manchester and was one of the top of my class in all of the programming courses (Java, C, C++, C with OpenGL) I have worked in the defence industry working on UAVs (aka Drones) and on the Julius Chinook helicopter and both of these were coded in C++ and Microsoft Visual Studio 2008. I spent a period of my time working on a legacy system written in Borlund C++ and converting it to a new system using Visual Studio. I also spent a period of time writing C in Eclipse on an embedded system (this was for the JULIUS Chinook project) I am extremely willing to negotiate on price and for English projects the language barrier certainly won't be a problem. I am extremely flexible and am always willing to work late or make additional changes or fixes as and when required. Fixes to problems can certainly be negotiated on price/time wise.
