JavaScript expert needed

We need a JavaScript expert for a browser based chat software. The chat is Flash based, running in the background, the JS code takes care of the rendering of each parties' messages in the browser. The chat is already developed but we have performance related and other issues with it, thus the lucky candidate's tasks will be the followings:

- optimize the JavaScript code massively (rewrite parts or in full if needed)

- speed up the rendering of the entire chat in the browser by taking care of memory hogs, and other performance related issues (garbage collecting, etc.)

- get rid of the unwanted and not needed functions, code structures, etc.

- if needed give advice and recommend necessary changes and modifications regarding the actual code or the programming logic

- document the code for further extensibility

- the code must be compatible with all major desktop browsers with the same speed and quality

The selected guy must have:

- a proven knowledge of how JavaScript is working in desktop browsers (must have working online references)

- experience with long running foreground scripts

- experience with how the quantity of text and the css effects affect the rendering

The project takes a couple of weeks at most, I don't care if you have a job or you just have an online portfolio for yourself, just let me know how good you are and show me you have the required skills. You'll work closely with Flash and PHP developers in CET timezone.

Thank you.

Beceriler: CSS, HTML, Javascript
