Project description:
"I want to launch a revenue-focused Android app and the first piece I need built is a rock-solid user-login module. The code can be Kotlin, Java, Flutter, or React Native—whichever delivers smooth performance—but it has to:

• handle secure registration and sign-in (email, phone, or a proven third-party auth such as Firebase)
• keep users signed in with reliable session persistence
• include simple onboarding screens that I can expand later

Please target Android 8.0 and above, follow Google Play guidelines, and comment your code so I can extend the project after this milestone. Deliverables are the full, buildable source code and an APK that I can install and test; the job is complete once the login flow runs crash-free on my device." (client-provided description)
