i need a app developer who can make apps for product sale like blinkit/zomato

I'm in need of an experienced app developer that can build a product sale app similar to Blinkit. Our app needs to be compatible with both iOS and Android platforms, and should include a shopping cart feature. We don't have a specific preference as to which payment gateway we should use, so any recommendations from the developer would be greatly appreciated. if he/she can make apps like zomato and blinkit then reach to me i need to have conversation
