We’re looking for an innovative and detail-driven Android Developer to build a production-ready mobile application with a sleek UI, seamless API integration, and smooth performance.
This project involves designing and developing an app from the ground up — combining modern Material You UI, secure authentication, real-time data, and offline support.
You’ll work closely with our design and backend teams to convert mockups into a fully functional Android experience. If you enjoy crafting intuitive interfaces, writing clean Kotlin code, and collaborating inside an agile workflow… this project will be a great match.
The app includes features like user login, product display, notifications, caching, and payment integration. You’ll get creative freedom in architecture decisions while following best practices for scalability and performance.
This is a 10–12 week project, with an extension possible for long-term maintenance.
Key Responsibilities
Develop Android apps using Kotlin and Jetpack libraries.
Integrate REST APIs and handle complex JSON responses smoothly.
Implement Material Design 3 for modern, attractive UI.
Integrate Firebase (Auth, Firestore, Storage, Crashlytics).
Build clean MVVM architecture with Use-Cases and Repository patterns.
Manage offline support using Room Database + caching logic.
Build payment integration (Razorpay / Google Pay / Stripe).
Implement push notifications with Firebase Cloud Messaging.
Handle app navigation with Jetpack Navigation components.
Ensure app responsiveness across all screen sizes.
Optimize performance (start time, memory usage, RecyclerView smoothness).
Write unit and UI tests (JUnit, Espresso).
Manage Play Store deployment & app signing.
Document code, APIs, and development roadmap.
Provide 15 days of post-launch bug fixes and support.
