    Richard Windsor

    Highly qualified and experienced UK based software developer

    United Kingdom - Last active: 1 day ago - Tests: 6 - Portfolio: 5

    I've been developing software as an employee and as a freelancer for over 15 years for a broad variety of applications from hardware drivers to high level multimedia systems. I've also been lucky enough to work in an industry that combines coding with media design so I am able to manage all aspects of a given job. I'm currently working with companies to build internet and intranet applications that improve their workflow efficiency. I develop bespoke applications from the ground up which allow the client to work as they desire rather than them having to conform to off the shelf software. My prefered development languages are PHP, XHTML/CSS, and SQL, although I'm also proficient in Javascript/AJAX, C++, and all forms of less savory HTML. On the media side, I am proficient at video editing, 3D modelling, animation, and image manipulation using a variety of software. I have worked with TV and film companies as well as being a TV studio manager responsible for all aspects of programme production.
