PHP developer to find database and performences issues on php e-commerce site

I am looking for a good developer, with great feedback history, who can help in fixing few issues on a php base (custom developed) e-commerce website.

As the product db is very large, the website is running on two server configuration, with 2 databases that are synchronizing information from one another.

The databases are not synchronizing and updates on the back-end panel are not being saved (like adding new products or making changes)

The website must be copied to another location to be dealt with. We cannot have any downtime.

I am looking for someone who could see the system, understand the problems and provide a solution.

Kỹ năng: MySQL, PHP
