I am expert in php and ruby on rails programming language. I have developed lots of websites using core php, ruby on rails, wordress, magento and phpfox. The website that you wants to develop is simple and we can easly develop in small timeline. In this website, we have to create the application like stackoverflow but in stackoverflow any one can give answers. we need to develop an app where a front end user can make a question and approved experts will provide the relevent answers. There will be three roles user, expert and admin. User can provide a question of specific cateogry and expert will serve that. Please discuss with me it is very interesting to develop.
