E-Commerce Mobile Android App

The mobile app is a digital assistant and service platform developed for a large hardware retailer, enabling customers to connect with experts through a modern mobile app backed by scalable cloud services.

Challenge

The Android app started as a greenfield project and required a solid architectural foundation to support a consumer-facing product with 5M+ downloads. In parallel, the platform needed a reliable and customizable video communication solution for expert consultations.

My Contribution

I was heavily involved in the architecture and foundational code of the Android app, enabling scalable and consistent feature development. As part of a breakout effort, I designed and built a customizable Android video call library based on AWS Chime.

Key contributions included:

• Android & Mobile Architecture

  • Co-designed the app architecture for a greenfield Android project.
  • Built core abstractions using Jetpack Compose, Navigation, deep linking, GraphQL, and Room.

• Video Call Library

  • Developed a reusable and customizable Android video call library based on AWS Chime.

Impact

The architectural foundations enabled the Android app to scale cleanly as features grew. The video call library reduced integration effort, sped up the development of new features and enabled the team to focus on delivering value to customers.
