I mainly code in PHP and JavaScript.

I use MySQL for my data storage. (I am learning to use Memcached for efficiancy)

I use the jQuery framework. (I am learning to use MooTools)

I also write in HTML5 and CSS3, and prefer JSON to XML (Although it is apparent that XML and JSON are both suited to different things and shouldn't be thought of as completely interchangeable!)

I have dabbled with the Facebook PHP SDK.

I am slowly picking up Git, it's a bit embarrassing so I won't link you to my GitHub just yet!

I have studied various PHP frameworks and currently feel that, while useful for a small application, for scalability, creating individual API's which can work together is a much better solution.

Anybody who is feeling helpful could always email me if you know anything about the things I am learning, maybe we could share anecdotes about the noob problems that I am facing!
