Barber Shop App & Website Development

I'm looking to develop a comprehensive mobile app and website for my newly opened barber salon. The primary function of these platforms will be to facilitate booking appointments.

Essential Features:
- Booking System: The core function should be booking appointments.
- Additional Features: I'd like to incorporate automated reminders, cancellation management, and a loyalty rewards program.
- Platforms: The mobile app needs to be functional on both iOS and Android.

Integration:
- POS System: It's crucial that a Point of Sale (POS) system is integrated with these applications. The POS needs to be fully up-to-date and functional for daily operations within the shop.

Ideal Skills and Experience:
- Experience in developing mobile apps for both iOS and Android platforms.
- Strong background in creating user-friendly booking systems.
- Knowledge in integrating POS systems with mobile apps and websites.
- Familiarity with implementing features like automated reminders, cancellation management, and loyalty rewards programs.
