I need a full mobile app built from the ground up that lets users connect, share content and chat in real time. The final product must run smoothly on both iOS and Android, so feel free to suggest whether you prefer a single codebase approach (React Native, Flutter, etc.) or separate native builds in Swift and Kotlin—what matters is reliability, speed and a modern UX. Core functions I have in mind include user sign-up/login, editable profiles, a swipeable feed for posts, image / video uploads, push notifications, direct and group messaging, and basic admin tools on the back end. I’m open to using Firebase, AWS Amplify, or a Node.js-based API if that speeds up real-time features and hosting. Design wise, I want a clean, social-first interface that feels instantly familiar yet fresh—nothing too cluttered, but definitely polished enough for App Store and Google Play review. Concrete deliverables: • Complete source code and project files • Testflight / APK builds for staged QA • Documentation covering environment setup, build steps, and API endpoints • A short hand-off call or video walkthrough once I’m ready to publish Please outline your proposed tech stack, estimated timeline, and any past social networking apps you’ve shipped. I’m ready to move quickly once I see a solid plan.
