I've been a part time desktop developer for the last 14 years starting with vba and moving on to C/C++ et al. My main line of work is CAD customisation and applications mainly focussing on Tekla, AutoCAD and Bricscad plug ins using C++ or C# with my focus being in construction (I have been in construction for 28 years).
I now work as a developer full time for myself and now also provide solutions for our clients on the web using php, javascript and mysql to create rich web apps and will be venturing into the mobile world with some of these in the near future.
