We have developed a single page application and it's now in alpha stage (view more about this here: http://www.johnpapa.net/spa/). We need an expert to perform the following tasks:
1. Optimize it for speed - will be tested using Google Test Page
2. Optimize it for all browser - it is currently works on chrome
3. fix bugs and improve the code
4. Implement infinite scroll plugin
5. test it, test it, and test it again until it works without bugs.
I will send a link to the staging site if I think you're qualified for this job.
