Confidential, Phoenix, AZ

Sr. iOS Developer

Responsibilities:

• Designed and implemented UI using XIB files and programmatic UI statements in UIViewController.
• Used standard iOS interface Components such as table view, navigation controller, various type of button and table cell, etc. as well as creating custom interface elements in the application
• Used REST web service with NSURLSession. Initially the application used XML format and later moved to JSON.
• Implemented Custom classes for web-service/ data-driven application architecture.
• Strongly used break points and NSLogs to track down the different issues in code implementation.
• For persistence of the information a singleton implementation of SQLite was used. For user defaults the app uses the NSUserDefaults class.
• Worked closely with the backend team to ensure a smooth transition from XML to JSON.
• Used Git as source control systems for code base management.
