React Native MVP with Payments

I have a complete mobile UI already sketched in HTML, CSS and vanilla JavaScript. I now need that design rebuilt in React Native so I can ship an installable app on both iOS and Android.

Scope at a glance
• Re-create the existing screens as React Native components.
• Wire them to Supabase Authentication and Database so users can sign up, sign in and store basic profile data.
• Implement both one-time and subscription-based payments—Stripe, in-app purchases or another cross-platform solution you are comfortable with.
• Produce release builds: an .ipa for TestFlight/App Store and an .aab for Google Play. Basic publishing guidance is welcome.

I will provide:
– The original HTML/CSS/JS files and assets.
– Supabase project credentials.

Deliverables:
1. Clean, well-documented React Native source code.
2. Working Supabase integration (auth & sample CRUD).
3. Payment flow that completes test transactions for both models.
4. Store-ready iOS and Android builds plus a short setup/readme.

Please include a brief outline of your approach and any similar apps you have shipped. I’m aiming for a lean MVP, so efficient, modular code and clear communication are key.

Will request NDA signature. Codeword for job: RTApp

Thanks
