Implemented latest features in MVVM architecture and refactored preexisting MVP architecture to MVVM to achieve a lifecycle aware application. Implemented
• Dependency Injection using Dagger2 to ensure dependency inversion as per the SOLID design principals. Encouraged an implemented TDD using various tools to create tests such as Junit, Mockito, PowerMock and Espresso for automated UI testing. Used ButterKnife on Java classes to implement view injection Used Firebase Analytics to track and log user behavior using the Firebase Console. Implemented features in both Java and in Kotlin, refactoring some older classes to Kotlin from Java and creating the latest features in Kotlin. Worked in an Agile software environment using Rally to ensure progressive and productive development.
