Server Application & Database

We are seeking a web developer to design and implement a back end server application and a user database to be hosted with Amazon Web Services.??

Task 1: Implement JSON queries that can be utilized by our front end iOS developer to interface with the server application. Provide these queries in a timely manner for testing in our mobile app. We expect some queries to be ready for testing by our iOS developer within 1-2 weeks after project is awarded.??

Task 2: Build an efficient MySQL user/network database to be hosted by Amazon Relational Database Service (Amazon RDS).?

Task 3: Design and implement a server application (hosted with Amazon Elastic Compute Cloud [Amazon EC2]) that can receive and respond to encrypted queries. Some queries will require advanced calculation, manipulation and analysis of data in our user database.

Task 4: Develop a push notification distribution system that integrates with Apple Push Notification Service (APNs) and Amazon Simple Notification Service (SNS).

Task 5: Create and update passes for use with Apple’s Passbook. To explore the Passbook Development Guide, Google search “apple passbook programming guide”??

Task 6: Validate the user's email address and phone number.

?- Generate an email verification code & link that is immediately sent to the user's email address. The link will be a custom URL that redirects to our mobile app. The code will be a randomly generated number.

?- Utilize a third party SDK (most likely Twilio, unless awarded freelancer recommends another) to perform phone number verification via call and text. To explore Twilio phone verification, Google search “twilio two factor authentication”

??Task 7: Fully integrate with Amazon Web Services (AWS). Perform testing to ensure accuracy of data and optimization of performance.???

Our Priorities:

?1) Security: industry standard encryption

2) Maximum Efficiency: optimal back end performance to result in a speedy user interface and efficient data management

?3) Seamless interaction: clear, easy to implement queries that can be provided to our iOS developer for plug & play server interaction?
