Hi,
I visited the given site and saw few errors like 403 forbidden, I guess there is some issue with 'oauth'(Authorization Tokens) token thing which needs to be fixed for your site to be working.
I have been working on MySQL, PHP , Zend and AngularJS for last 7 months, building and using REST API as well as RPC service. Currently our product is used by Westpac New Zealand Bank. Right now I want to learn and build myself up in this field, so money is not a primary thing for me, it's all the experience I need.
