Android Pro Networking App Build

I’m developing a professional-networking platform exclusively for Android and need the full application coded and ready for launch on Google Play. The core experience centres on meaningful professional connections, so fluid in-app messaging is essential. Users must be able to start one-to-one or group chats instantly and exchange photos or short videos without noticeable delay or quality loss. All accounts will be created and secured through phone-number verification; no email or third-party social logins are planned, so the onboarding flow has to handle SMS code delivery, validation, and graceful error handling. Once inside, users can update a quick profile, search or receive suggestions, start a chat, and share media directly from the camera or gallery. Backend architecture, database design, and any real-time services (Firebase, Socket.IO, or your recommended stack) should be implemented so the app scales cleanly from an MVP to thousands of active users. Clean, well-documented Kotlin or Java code, responsive layouts for common screen sizes, and concise API documentation are part of the final hand-off. Test builds should be supplied throughout the development cycle so features can be reviewed in context.
