We’re looking for an Android Developer who builds apps that feel smooth, intuitive, and truly “native” — the kind of developer who understands that great mobile apps aren’t just functional… they’re experiences.
This project involves building a feature-rich Android application for an emerging consumer-tech brand. Think:
✔ Modern Material 3 UI
✔ Offline-first architecture
✔ Real-time Firebase sync
✔ Deep API integration
✔ Background services + notifications
✔ Payment flow
✔ Highly optimized performance
You won’t just write screens.
You’ll shape the entire mobile experience.
We’re looking for someone who thinks like a product engineer — someone who understands UX, architectural decisions, user behavior, and how small micro-interactions can transform the feel of an app.
This is a 10–12 week project, with potential extension for post-launch improvements, analytics-based optimization, and new feature releases.
