Tech Stack

Frontend (Android):

• Jetpack Compose: Declarative UI toolkit for building native Android UIs.
• Clean Architecture: Ensures maintainability and scalability by dividing the code into clear layers.
  • Presentation Layer: Jetpack Compose and ViewModels.
  • Domain Layer: Use cases and business logic.
  • Data Layer: Repositories and Room Database.

Backend:

• Node.js: JavaScript runtime for building fast and scalable server-side applications.
• Express.js: Web framework for handling routes and APIs.
• MongoDB: NoSQL database for efficient and flexible data storage.

Hosting:

• Render: Hosting platform for the backend, providing a public API endpoint accessible from the Android app.
