I need a complete Android-only social networking application built from the ground up. I will rely on you to handle everything—user-friendly UI/UX design, native Android development, backend setup, and thorough testing—so the product is ready for release on Google Play. Core concept Users must be able to create accounts, build profiles, post text, photos or short videos, follow one another, and interact through likes and comments. A real-time feed and basic push notifications are essential for engagement. Secure authentication, scalable cloud storage for media, and an admin panel for moderation also form part of the scope. Preferred stack Kotlin or Java for the Android client, paired with a backend you are comfortable maintaining (Firebase, Node/Express, or similar cloud-ready solution). Feel free to suggest an alternative if it speeds up development and keeps costs reasonable. Deliverables • High-fidelity UI mock-ups for approval • Full Android source code with clear documentation • Configured backend (database, storage, authentication, APIs) • APK ready for Play Store submission • Test report covering functional, UI, and performance checks Acceptance criteria The APK must install on Android 8.0+ without crashes, pass Google Play pre-launch reports, and support at least 1 000 concurrent users in load tests. Timeline and milestones can be broken down around design sign-off, beta release, and final hand-over. If the launch is smooth, I may later commission an iOS version, so clean, reusable architecture is appreciated.
