I’m ready to build the first release of my Android application and need a developer who can take it from zero to a functional APK. The initial scope is focused and clear: • User Authentication – new-user registration, email/password login, secure session handling, and password-reset flow. Everything else can be minimal for now (a splash screen and a basic home screen are fine); the goal is to deliver a clean, well-structured codebase that lets me bolt on new features later. I’m happy with Kotlin or Java as long as the project is set up in Android Studio, follows current Android SDK guidelines, and uses best practices for security and architecture. Once the authentication flow is working smoothly, I’d like a quick walkthrough of the code so I can maintain or extend it myself. Please include any relevant Firebase/Auth0/OAuth experience in your reply and let me know roughly how long you expect the build, testing, and brief hand-off session to take.
