Build, test, and deploy the core cross-platform mobile app (iOS & Android) using React Native with TypeScript.
Implement key app features: video product upload/playback (React Native Video/ExoPlayer), live streaming (Agora/Twilio), and secure payment flows with various providers (MTN, Flutterwave, Paystack, M-Pesa, Visa, etc).
Manage app state efficiently using Redux/MobX and integrate essential services: Firebase Cloud Messaging for push notifications, and maps/real-time features (Google Maps/Mapbox) for tracking.
Ensure performance, quality, and maintainability of the application, with consideration for PCI compliance in payment modules and low-bandwidth environments.
