    Jamie Reid

    Senior Java and C++ Software Developer

    Spain - Last active: 1 day ago - Tests: 8 - Portfolio: 2

    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) My core skill set includes the following skills: C, C++, JavaSE, JavaEE, JavaFX, Ant, Maven, SQL (MSSQL, MySQL, Oracle), Bash Shell. I have worked with the following IDEs: Visual Studio, Eclipse, IntelliJ, NetBeans and I am happy to work with any source control system. I am happy to work both Windows or Linux operating systems. 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.
