PROFESSIONAL EXPERIENCE:

Confidential, Baltimore, MD

Android Developer

Responsibilities:

• Worked in different phases of project life cycle like design, development and testing of application for Android mobile devices.
• Responsible for designing the architecture of this application which is used in android platform.
• Implemented Kotlin with Android content providers for implementing features like sending E-mails, SMS, etc., from the app and designed suitable GUI for these applications.
• Responsible for SERVICES, ASYNC tasks and Alert Notification API to implement event reminder feature into the mobile app.
• Understanding hardware features of ADT and Confidential related sensors and alarms to have a control on them through the application.
• Working closely with Localization team to support application in about 45 languages with RTL support.
• Bug tracking and issue resolution Documentation (logged in ATLASSIN - JIRA Agile, CONFLUENCE) for support turnover weekly
• Used HTML5, CSS, Java script, Angular JS to develop hybrid apps.
• To work with web views on Android used Espresso-web as an entry point. Espresso-web is an entry point to work with WebView’s on Android. It uses Atoms from the popular WebDriver API to introspect into and control the behaviour of a WebView.
• Integrated Android Pay and PayPal payment gateways to provide payment options.
• Handled XML data using efficient parsing techniques such as DOM parser.
• Refactored the legacy code with Dagger dependency injection library to create reusable, testable interchangeable modules.
• Used Butterknife and Dagger 2 for views injection and loose coupling.
• Designed screens using MVC pattern for the application with Android Studio IDE.
• Developed the SQLite database to store and display data when application would be offline.
• Implemented RxJava Validation for customer registration and Login forms.
• Improved the current data model architecture by using MVP pattern and also used Dagger 2 dependency injection to avoid hard coupling.
• Used Github for version control and Jenkins for continuous integration.
• JIRA tool was used for bug reporting, task allocation and tracking the progress of the project.
• Used Junit and Mockito framework for Unit testing and used Espresso Framework for UI testing for screens like login screen, add to cart screen, list of products screens.
• Developed the UI screens using Android SDK and Eclipse plug-in to support Portrait and Landscape modes.
