React Native Dev Needed to Configure/Finalise Healthcare App

* NO AI GENERATED PROPOSALS PLEASE**

I’ve built a mobile healthcare app in Create.xyz and exported the full working code. The UI and logic are mostly complete, but I need someone to help configure and set up the features securely and professionally.

The tasks include:
• Setting up my own Stripe (15% admin commission logic)
• Adding environment variables to secure API keys
• Connecting Google Maps API for location tracking
• Setting up a live chat API (Twilio, Firebase or similar)
• Configuring email notifications (e.g. SendGrid, Firebase)
• Testing and refining user login and permissions (admin, professional, client)
• Debugging any logic issues from the export
• Helping with Apple App Store & Google Play submission if possible

You do not need to build the app from scratch — I’ll provide all the exported code.

Looking for someone with:
• Strong React Native experience
• Stripe or similar payment experience
• A good understanding of security and GDPR
• Solid communication and speed

Please include examples of similar work, and your rate or fixed-price quote.
