PROFESSIONAL EXPERIENCE:

Confidential

Senior Android Developer

Responsibilities:

• Worked on a codebase built on MVVM with the Android data binding library, the new Architecture Components and Kotlin.
• Implemented a methodology based on TDD to increase code coverage and frameworks like JUnit, Mockito, Robolectric and Espresso.
• Code was decoupled using an architecture with Dagger 2 and dependent components with custom scopes.
• Generated a reactive application with a Repository pattern and RxJava subscribing Consumers from the ViewModels.
• The network stack was based on a Facade pattern using Retrofit, OkHttp, GSON and custom interceptors.
• Implemented the local data sources using Room and LiveData generating a lifecycle-aware application.
• Worked on a proof of concept using the Android Instant Apps that allowed the user to preview the content of the app without installing it.

Environment: Android Studio, Java, Kotlin, Oreo, Dagger, Retrofit, RxJava, MVVM, Junit, Mockito, Robolectric, Espresso, OkHttp, Architecture Components.

Confidential

Android Developer.

Responsibilities:

• Rewired the code in order to implement the Marshmallow API runtime permissions and Nougat Picture and Picture and Multi-window.
• Implemented an application based on MVP and Dagger 2 to increase testability and code decoupling.
• Worked on a network stack based on Retrofit and RxJava2 and RxAndroid Schedulers.
• Migrated a codebase from RxJava 1 to RxJava 2 to be able to handle backpressure with Flowables on repetitive data.
• The JSON serializers were based on the Jackson library, a proof of concept was made with Moshi to remove the reflection.
• The code coverage was increased from 20% to 50% using unit testing libraries based on JUnit and mocking practices (Mockito and Powermock).
• Implemented the push notification modules using Firebase Cloud Messaging with custom audiences and topics.

Environment: Android Studio, Java, Dagger, RxJava, Jackson, Firebase, Marshmallow, Nougat, JUnit, Mockito, MVP.
