WORK EXPERIENCE:

SENIOR ANDROID DEVELOPER

Confidential, Seattle, WA

Methodology: XP Programming, TDD

Responsibilities:

• Converted the data model, api communication service layer and view UI layer to Kotlin programming language and JetPack library
• Used the Data Binding Library to support two-way data binding to receive data changes to a property and listen to user updates to that property at the same time
• Created custom and compound views to show Breaking news and live video alerts data returned after parsing
• Worked with external client to in corporate FreeWheel sdk and Nielsen proprietary measurement sdk for monetization features
• Improved live video playback performance and fixed some display issues with the widget within the application
• Pair-programed to use Urban Airship SDK to in corporate messaging and content delivery tools, including Push Notifications, Rich Media Messaging, In-App Purchase and Subscriptions
• Stream favorite Confidential and MSNBC shows using ExoPlayer MediaPlayer API for adaptive playback, media composition and caching
• Coded using ReactiveX programming to compose asynchronous and event-based programs, avoid intricate stateful programs, using clean input/output functions over observable streams
• Wrote test cases using JUnit /Mockito testing frameworks for model and viewmodel layer
• Worked closely with the external designer team to import the assets correctly through Invisio and Zeplin web platforms

ANDROID SPECIALIST

Confidential, Brookhaven, GA

Methodology: Agile, Scrum, TDD

Responsibilities:

• Used ReactiveX API for reactive programming with operators to transform, combine, manipulate, and work with the sequences of items emitted by Observables with schedulers
• Changed app architecture from MVC to new lifecycle aware Architectural components of LiveData, ViewModel and Room
• Created a Widget on home screen to show the latest rain alert for current or chosen location
• Build Location Services in the app to get the current location, get periodic location updates, look up addresses, create and monitor geo-fences, and detect user activities
• Added Google In-app purchasing and Amazon In- app purchasing library to buy Premium services for HD maps and unlock more rich features

• Independently worked on parsing XML data returned by Rain API, Wind speed API and Local temperature API
• Provided continuous improvement through creative solutions to glitches in synchronisation, asynchronous APIs, and leveraging offline features

ANDROID PROGRAMMER

Confidential, San Francisco, CA

Methodology: Agile, continuous Integration with scrum

Responsibilities:

• Divided the application into at least three different layers and take most of logic out from the activities so that we can test it without using instrumentation tests in MVP architecture
