Do you have any questions about the job description?
Hi, sure I have a question. Do you know that to make it, you'll need a registered APP (with API credentials) in Facebook, to make post on your page?
Proposal:
Can be done. If your website on Wordpress CMS, it would be better to make plugin for that action (autopost reviews). I have previous experience with facebook api, so I can help you.
Also, it needs to install FB PHP SDK on your website.
