Uber for Food Delivery - Mobile App Development (iOS & Android)

Looking for a full stack developer who can build a scalable mobile app, frontend and backend. Payment will be paid based on milestones and will only be released once the entire project is complete. Please do not bid if you haven’t reviewed the requirements below and do not agree with this payment structure. Ideally the candidate would already have a good starting point i.e. source code from previous work. This would reduce the overall project duration and allow more time to be spent on customisation and improvement. This app would work very similarly to UberEATS, however the orders would go to the drivers and not the restaurant. Current plan is as below - unless if developer has any suggestions that would make more sense: Either truly native (iOS Obj-C/Swift and Android Java), or React Native (JavaScript) if you can do it flawlessly Firebase Backend for scalability MongoDB, NoSQL database for scalability Provider App, Customer App, Store Keeper App, Admin Panel Push notification, both in-app or when app is closed Offline capability Modern UI/UX Lightweight, fast Account types - Providers, Customers, Store Keepers, Sub Admins, Admins: Providers are able to accept up to 3 jobs from restaurants in the same location, but priority will go to those who are available/free. Providers will call or physically place the order at the restaurant but this is done outside of the app. Providers can then update the order based on actual price/availability, etc. Updates order status i.e. order confirmed, picked up, on the way, delivered. Can update location instead of keeping GPS on. Job offer will display pick up location, drop off, distance, order details, quantity and bill amount. Customers place order through menu on the app. Can see nearby stores, popular stores, etc. for user friendliness; or they can search on the map. Once a Provider accepts the job they will place the order for the Customer and the order will be finalised only after the Provider has placed the order with the restaurant. Customer can reject the Provider. Store keepers are premium accounts on either monthly membership or commission based. Admins and sub admins can create stores (restaurants/food trucks/food stalls); stores/menu/address/etc. can be created using Excel import or text file, etc. Sub admins are employees working for App company. Individual access level and job titles can be customised by Admin. Admins will have full access to everything; Must be able to provide all the features that Uber and UberEATS have as a minimum: Native IOS App for Provider and Customer Native Android App for Provider and Customer Mobile Responsive Front End Website God's Eye - Real Time GPS Tracking Promo Code / Campaign Management Pay using Credit/Debit Card, Cash or Wallet Balance Book for Later with Dispatch Google Map Integration Real Time Vehicle tracking, including food trucks and stalls Registration Facility in Website Automatic Fare Estimate & Calculation Tipping Feature Stripe Payment Gateway Paypal Payment Gateway Select Provider vehicle type User can Invite Friends In-app Notifications to Provider and Customer Facebook Signup and Signin Facility Ability to choose vehicle type Favourites location Option for the Provider Export Reports History Details Social Sharing Feature Review and Rating for both Provider and Customer Surge Pricing Share ETA SEO Settings in Website SEO Friendly Front End Website Email Templates User Friendly Admin Panel with Privileges Accept / Decline delivery Request In-app voice call Easy Commission Tracking Management in Admin SMS notification Push notification Add/Save Location/Restaurant/Address using GPS or manual input Feedback and Ratings Provider registration Account / Profile Show busy areas and price surges Payment management and statistics Auto payout system Tutorial page for new Provider / Customer / Store Keeper Providers can receive a ‘verified’ symbol when they submit certain documents and have completed a few deliveries"
