Hello, my name is Oleg, I am a web developer and I'm in top of PHP, Drupal and Wordpress tests in Freelancer.
I have broad experience in this field, you can kindly check my latest work at: http://www.mycustombook.com. Im ready to take your project and work on it with care, flexibility and provide max possible quality. My proposal as of an expert is to use Drupal platform for the reason of its obvious advantages among the other platforms, such as: flexibility, enhanced security, constant developers support etc. To make sure you can google - Magento site, the White House, NY Stock Exchange etc., they are Drupal based, but other platforms can be used, it's up to you,
Have a nice day,
Oleg
