As a senior iOS developer, I have worked for more than 3 years to develop enterprise iOS application. Also I have been working for an eCommerce company for almost a year. The CMS is Magento and WordPress. Although most time I work as iOS developer, I am quite good about PHP and MySql. Especially I am very good about web service integration (REST, SOAP etc.) with a lot of platforms (Magento, Google, Facebook, Paypal, Alipay, Wechat etc.). By the way, it's my first time to bid in freelancer.
