I need a focused Android build that lets users sign up or log in securely and receive real-time push notifications. The core of the job is to: • set up robust user authentication (email / password and social login options are both fine as long as they follow current Android best practices); • wire the app to a reliable push service—Firebase Cloud Messaging is my default choice, though I’m open to an alternative if you can justify it. Everything else—UI polish, extra features, store submission—can follow later. For now, I want a clean, well-structured codebase that I can extend. Please use Kotlin where possible, document the key classes, and make sure the build runs without errors in Android Studio. Deliverables 1. Full Android Studio project folder ready to build and run. 2. Clear README covering setup, authentication flow, and how to test push notifications. 3. Short video or screenshots proving both features work on a device or emulator. I’ll review by installing the APK, creating a test account, logging in, and pushing a dummy notification from Firebase to confirm it arrives. If that round-trip works smoothly, the milestone is complete.

Hi there, Looking at the scope, this is really about getting two core systems right before adding anything else later — secure user authentication and reliable push notifications. I would implement the authentication flow in Kotlin using modern Android architecture, supporting email/password login and social sign-in if required, and use Firebase Cloud Messaging for notifications since it is stable, well-documented, and easy to extend as the application grows. Once completed, I will provide the Android Studio project, setup documentation, screenshots/video proof, and clear instructions so you can easily test account creation, login, and notification delivery yourself. One thing I would like to clarify is whether you already have a Firebase project configured or if that setup is also part of the scope. Thanks, Rahul A.

Hi there! Firebase Auth + FCM integration done right — clean token refresh, background/foreground notification handling, and a Kotlin codebase you can actually extend — is exactly our kind of focused build. Deliverables: - Kotlin Android Studio project — MVVM, proper separation of concerns - Firebase Auth: email/password + Google Sign-In (social login, best-practice flow) - FCM integration: foreground + background push, notification channels, token management - README: setup steps, auth flow walkthrough, how to trigger a test notification from Firebase console - Short screen recording showing signup → login → push notification received The build will run clean in Android Studio, pass your APK install test, and be structured so your next developer can slot in UI polish or new features without touching auth or notification logic. I'll personally verify the full round-trip before handover. One question: do you need data persistence after login (Room/SharedPreferences for session state), or is a clean stateless auth flow sufficient for this phase?

Hey, Clean auth foundation with FCM push notifications — the right way to start a project before adding features on top. Kotlin, Firebase Auth for email and Google login, FCM wired and tested, well-documented codebase ready to extend. APK, README, and a short demo video showing the full round-trip included. Quick question — do you need social login from day one, or email and password first with social login added later? Let’s get your foundation solid. — Pooja

⭐ Hi there ! A clean, extensible Android codebase with auth and FCM push notifications is exactly the right foundation to build on before adding UI polish and extra features. I've built Kotlin Android projects with Firebase Authentication, social login, and FCM push notifications - well-structured, documented code that another developer can extend without untangling the architecture. One similar foundation project I delivered had the client adding new features in the next sprint without touching the auth or notification layers. Full Android Studio project, README, and proof screenshots included as standard. Do you need social login from day one or email/password authentication only for this milestone - so I can scope the Firebase setup correctly before starting?
