Highly experienced Javascript & PHP developer to review and improve existing code

I have a visualisation web app that allows artists to create digital mockups of their artwork in different virtual rooms. They can manipulate these mockups (ie. change the shadowing, the lighting, furniture colors etc).

Once they have created their mockup, they then save it and download it. But here lies the problem.

Saving and downloading takes an incredibly long time and current users are finding it a little too challenging and frustrating to use, as initially intended. Everything else on the web app seems to be working fine.

My developer has been putting this code together for the past few months, and is working very hard in getting the code right, but he will need someone to help him out and possibly even to rewrite some parts from scratch.

I am after someone who is an expert coder in Javascript & PHP (must haves). As the title states, you need to have lived and breathed these two languages.

As part of this job, I will need you to go into my github repository, to check and review the code. You will need to make improvements to the code that will result in speeding up the saving and downloading processes. There'll also be an opportunity to make changes to the code that will result in a better / cleaner user experience.

In order to be considered, please answer the following 5 questions:

1. How many years experience do you have with PHP, and how many years with Javascript?

2. You must have a public repository at Github or Bitbucket that i can review. Can you please attach the link to it?

3. Would you be available for a face to face interview over Skype soon?

4. Can you give me an indication of how you have / are living and breathing PHP & JS coding? :)

5. This is not as relevant, but have you ever worked on functionality similar to what I described?
