Sr. iOS Developer

Responsibilities:

• Actively participated in gathering business requirements to implement functional and technical specifications.
• Created custom UIAlert Controllers dat allowed you to insert your own Views created in interface builder. It was designed to look aesthetically identical to UIAlertController.
• Gathered visual customer data, and stored on a mobile device via Archiving.
• Migrated app from iOS 8 to 9 and made changed to accommodate the latest features and deprecated APIs.
• Created swift prototypes to test efficiency, but project was done fully in Objective-C; dis is due to the importance of proving to the FDA dat the Apps we are making are safe and dat every class does wat is intended by vigorous unit testing, integration testing and functional testing.
• Worked close with iOS team and UX team to gather function/feature requirements and work out implementations. Also was in charge of making unit tests for classes to automate expected use cases and verify dat edge cases are handled appropriately.
• Mocked Objects with OCMock and swizzle methods to halp test classes in unit tests; integration tests created to test complex UI interactions using XCTestCase, OCMock, and swizzling.
• Migrated away from using KIF for integration testing and replaced them with lower level testing.
• Created Documentation using IBM Rational DOORS to describe new classes, modified classes, and deleted classes. Linked each class with a feature requirement.
• Determined the amount of risk associated with each class and created unit tests for high risk classes; additionally contributed code fixes and code feedback in weekly code reviews.
• Created UI in Interface Builder using Storyboards, XIBs, and IBDesignable dat match the project specifications; Facilitated app distribution to iOS devices through a web browser using an internal server.
• Created and converted common code into its own Framework to halp modularize and simplify its distribution in the app; also participated in the localization of the App.
