I have been working on this project over the last 3 year. A project that is never ending and is very much in constant development.
I have and are working with alot of stuff, like:
* HTML5 / XHTML
* CSS3 / LESS / SCSS
* JS (jQuery, vanilla, angular and so on)
* Technologies research and development
* Task runners (Gulp and Grunt)
* Design
* POC (Proof of concept)
* UX
* MVC.net C#
and the list goes on and on
