Comprehensive Meal Delivery App Development

I am seeking an experienced app developer to build a meal delivery app for both iOS and Android. Key features and functionalities include:

User Account and Management:
* Ability to create and log in to an individual account.
* Account management options such as profile creation, reviewing order history, and saving multiple addresses.
User Roles
* Delivery Queue
* Payment gateway
* Super User - can create update and delete without restriction.
* Admin - can create update and delete. Cannot create, update or delete a super user or admin. Needs
confirmation from super user to delete a user.
* Customer - can create an account and subscribe. Can create a schedule. Can add items to schedule. Can review schedule. Can checkout. Can update schedule of items minimum of 3 days before delivery.

Some business rules.

If a customer is updating scheduled items days before the delivery. Even though the items were already pay for if the user removes items a credit balance is visible and tracked in real time. So the user can choose to add different items or use at a later date.

The ideal freelancer for this project should have excellent skills in iOS and Android app development, with a history of creating apps that support user accounts and a variety of management features. Familiarity with the food industry or meal delivery apps is a bonus. Please share examples of similar apps you've developed or contribute to, specifically those with user account management features.
