PROFESSIONAL EXPERIENCE:

Lead Android Architect

Confidential, San Jose, CA

Responsibilities:

• My greatest accomplishment was image rendering. I was able to successfully render 4K images in an Android app with is natively only capable of a resolution of 1080p.
• I was successful in another challenge: I kept TV and Tablet apps synchronized in the projection of car images rotating 360 degrees and in the interior panorama view in terms of direction, position and changing colors and wheels. This is not a mirroring process.
• I used Android Studio 3.0 as the IDE for development of the Android mobile apps in Java using MVVM architecture throughout.
• The project team consisted of one product manager, in China, one project leader who was also in charge of 5 other projects, and two Android developers.
• The Android development team consisted of only two developers. I served as lead, providing mentoring and assistance to one junior Android developer.
• Used Fir.im for Play Store approval and deployment
• Maintained Android app quality in development through continuous integration process using GitLab.
• Followed Google material design guidelines.
• Used Jira for documentation, task tracking, backlog management, and meeting prep.
• Used Dagger 2 for Dependency Injection.
• Automated testing with Espresso.
• Implemented back-end integration with proprietary SDKs which communicated with all Android platforms.
• Developed the Android app using Android Nougat (version 7.1)
• Managed threading, performance, and memory management with ExecutorService to handle download of more than 1000 files (images and videos).
• Using multithread setting limit of 3 in the ExecutorService, optimized the quad-core microprocessor contained in the devices.
• Because 90 % of images and videos used in the project were UHD 4k, memory management was a crucial point. Both applications run smoothly and are well optimized.

Environment: Android SDK, Android Studio, Java, GitLab, fir.im, Flurry Analytics, VrPanoramaView, Google SDK, RxJava 2, EventBus, Dagger 2, Retrofit 2, GSON, Zxing, BindingCollectionAdapter, RxPermissions, Flurry Analytics, Glide
