I need a mobile-first social networking application whose initial release focuses on one core experience: fast, reliable user-to-user messaging. I'm picturing a clean, intuitive chat interface—think read receipts, typing indicators, push notifications, and end-to-end encryption—without the distraction of full profile pages or a scrolling activity feed at this stage. My priorities are: • Native performance on both iOS and Android (React Native, Flutter, or true native—open to your recommendation) • Secure authentication and encrypted message storage • Scalable backend (Firebase, Supabase, AWS Amplify, etc.) with real-time updates • Well-structured, documented code so new features like profiles or feeds can be added later with minimal refactor Deliverables will be the compiled apps, source code, and a brief hand-off guide covering build steps, environment variables, and any third-party services configured. Once I can install the app on test devices and exchange messages seamlessly, the job is complete.
