Full mobile app development – beauty booking app (Android & iOS)

Hi, I’m looking for a mobile app developer (Flutter or React Native).

I need a COMPLETE mobile app for my beauty business (nails, PMU, beauty services).

The app must work on BOTH platforms:
– Android
– iOS

Main features required:
– Login / registration (personal code, name, phone number)
– User profile
– Appointment booking system
– Calendar with available dates and time slots
– Admin panel to manage bookings and users
– Notifications (appointment confirmation and reminders)
– Clean, modern and elegant UI (beauty / pastel style)

Delivery required:
– Full source code
– Android APK
– iOS build (TestFlight or equivalent)

I already have:
– a clear idea of how the app should work
– UI style references
– existing backend or code reference (can be reused if needed)

I need:
– a fully working app
– clean and organized code
– communication during development
– bug fixing and testing before delivery

Please contact me ONLY if you have real experience with:
– full mobile apps
– Android & iOS development
– booking / calendar systems

When you message me, include:
– similar apps you already developed
– the technology you suggest (Flutter or React Native)
– estimated development time
