    I am a 24 year old web application developer from Brisbane, Australia - although I'm currently based in Edinburgh, Scotland. I have a Software Engineering degree, and about 10 years of industry experience. (5 in programming and web, 5 in general I.T. support) If you're reading this, hopefully you're interested in giving me some work. I really love my job - making web applications is *fun*. I'm always keen to work with talented, passionate and like minded people, so please get in touch if you think we'd work well together.

I am also starting to experiment with developing my first Chrome Extensions, Android Apps, and Google Marketplace Apps. I'm a bit of a Google Fanboy and love working with their APIs. http://www.simonlang.org/
