• Efficiency was a priority, as I reduced surface and texture leaks in custom views using OpenGL ES fragment vectors. I even created a 3D Personal Assistant character using OpenGL ES and augmented reality modules.
• To control various internal features, I developed an efficient C++ API that communicated with Native Android libraries. For monitoring and analysis, I used Kibana and MDM to install and track applications on custom Android devices.
• In terms of development tools, I utilized Jenkins for continuous integration, GIT for version control, and GITLAB and SourceTree for streamlined workflow between the integrated development environment and the repository.
• Multi-threading was a focus for managing network and background operations, and I optimized 2D graphics rendering using OpenGL ES and C++. Dagger2 and Butterknife were employed for dependency injection and code reduction.
• Project documentation was maintained using Java Docs and Atlassian Confluence, and I created comprehensive app-specific documentation. JIRA was the tool for bug tracking and project workflow management.
• Analytics played a significant role in my work, as I tracked user interactions with the app using EventBuilders and click and selection listeners. I also handled debugging using ADB logcat and DDMS and conducted unit testing and instrumentation testing with tools like Junit, Espresso, and Mockito

I achieved:

• Pioneered the development of a groundbreaking custom analytics framework, akin to Localytics, which systematically captured user interactions throughout the app. The framework intelligently determined customers' areas of interest by considering factors like region, weather, and the time of year. This innovative solution empowered us to pinpoint the most valuable products and devise highly engaging and tailored ads, resulting in a substantial boost in ad revenue.

I did:

• Full-stack app development covering design, enhancements, debugging, and testing.
• Adhered to Material Design principles and followed the MVP pattern. Created rich UI elements for various app modules, incorporating Custom ListView, ScrollView, RecyclerView, ViewPager, and Navigation Drawer.
