Mobile App Developer Needed — Social Commerce / Live Shopping App

I want to launch a mobile experience that blends live-stream shopping with seamless, in-app purchasing—think TTS. The build must ship for both iOS and Android from day one, with user accounts that can authenticate either through email/password or the major social platforms.

Core functions I need working flawlessly:
• Real-time live streaming where hosts can pin products on screen
• A browsable product catalog that stays synced with my backend
• One-tap, secure checkout inside the stream and in the catalog view

Because I do not have a fixed preference on framework, you’re free to recommend React Native, Flutter, or any stack that delivers smooth video, stable commerce flows, and maintainable code.

When you reply, please include:
• Direct links or store listings for similar apps you have shipped
• Your suggested tech stack and reasoning
• A milestone-based timeline from kickoff to App Store / Google Play submission
• A ballpark cost broken down by major phase (design, development, QA, deployment)

I’m ready to move quickly once I find the right partner, so showcase your best live-commerce work and let’s create something great.
