Currently contracting for Mozilla - building http://builder.addons.mozilla.org/
I'm also working on my own project for front-end devs - http://jsfiddle.net/
More than 10 years of commercial experience gave me the ability to grew with technology as it evolved. My first websites were found in Yahoo before Google started their first indexing. It was a long way from simple static pages to full featured web applications we have now. Last few years gave us (developers and users) new revolutionary tools - social networking and decent frameworks to write them.
