HiI seeking expert iOS developer to help me extend my existing iOS app capability.He/she is required to have strong PHP experience to build the necessary web service (JSON) to complete the project. (existing i have a list of web services, developer will need to confirm if the existing ones can complete the project or not. If not, developer will need to build accordingly) We have APNS working on our existing app and we need to enhanced further with more complex tasks. Developer must have experience with APNS technology.Further details on the project will be given to interested developer only.Some clause to take note:1) No upfront payment. i do not provide upfront payment and i will only work with developers from escrow service only2) If there is need for web services, you will be responsible in building it.3) You will be responsible for providing the interface graphic required.Experience iOS developer only - need to know APNS, JSON, PHP and etcThanks
