Fast food Mobile App, AI-Driven User Behaviour

I'm seeking a skilled app developer for building a mobile app that provides user behavior predictions. This app should be developed for both iOS and Android platforms.

Utilize AI/ML technologies to create a mobile app for my fast-food shop, with the primary objective of enabling users to scan and pay. Ensure that each outlet has a unique barcode. If a user is unsure of the item price, incorporate a tag that, when clicked, displays the payment amount automatically. Given our multiple outlets, users must physically visit our store. Include a referral option, allowing users to invite others and earn reward points that can be utilized in their subsequent orders. Implement location-sharing features to assist others in discovering the locations of our stores.
