Cross-Platform Social Media App

I’m ready to commission a polished, production-ready social media application that runs natively on both Android and iOS. Flutter or React Native are both acceptable; whichever you choose, the final experience must feel seamless, fast, and secure.

Core scope
• Modern, intuitive UI/UX that mirrors the best consumer apps
• User registration and login using email/password, social-media OAuth, and phone-number OTP
• Real-time feed with profiles, posts, likes, and comments
• Push notifications (Firebase Cloud Messaging or comparable service)
• Embedded product listings and a lightweight shopping cart so users can showcase and trade items inside the social environment
• Robust database/back-end integration (Firebase, Supabase, or a custom REST/GraphQL API)
• Clean, well-documented codebase ready for future scaling

Deliverables
1. Fully functional Android & iOS app, store-submission–ready
2. Complete source code in a private Git repo
3. Build/deployment and environment-setup documentation
4. Post-handover bug fixes for an agreed support window

When you reply, please include:
• Links to live apps or Git repos that prove comparable experience
• A milestone-based timeline (design, MVP, beta, release)
• Your estimated total cost and any assumptions behind it
• The stack you intend to use and why it’s the best fit

I’ll shortlist quickly and would like to start as soon as we align on scope and milestones.
