I'm Charles. I'm looking for contract or fulltime. Local to San Francisco. I run http://jsonip.com http://jsonip.com and created Helium CSS. Been doing web development for 10+ years. Have a lot of experience doing full stack development with Python/Django, Node.js, and php a long time ago. Javascript is my main language these days. Primarily have been focused on frontend development, so I know how to optimize the hell out of what's delivered to the browser. Very good at writing cross-browser code, though fortunately IE isn't as much of an issue these days. I've done quite a bit of mobile-focused development using html5/css3 for multiple platforms. Have also done some work with Phonegap to publish apps on the Apple App Store. I also like writing tools to help other developers do their jobs better.
