Hyperlocal Marketplace App Development

I'm looking to develop a hyperlocal marketplace app (similar to Amazon with Zomato-style delivery) that connects customers with nearby stores via PIN code mapping for same-day delivery.

The project includes:
- Customer App (browse & order)
- Features: Product reviews and ratings, Wish list, Order tracking
- Seller App (manage inventory & orders)
- Delivery App (pickup & deliver)

Requirements:
- The apps should be developed for both iOS and Android platforms.
- Integrate Razorpay as the preferred payment gateway.

Ideal skills and experience:
- Mobile app development for both iOS and Android platforms
- Experience with Razorpay integration
- UI/UX design for a seamless user experience
- Background in building marketplace applications

Please provide a portfolio showcasing relevant projects.
