Personal React Native Courier App with Inventory, Orders & Lightweight Backend

I’ve created a local React Native delivery app for personal use. It allows two roles: Sender and Courier. Most of the features already work, but I want a freelancer to help finish and polish the app, and optionally connect it to a lightweight backend (like Firebase or a local Node.js server).

Features that are already built:

• Account creation (username & password)

• Role selection (Sender or Courier)

• Link users together via username

• Set inventory for couriers (products: rood, geel, blauw, snoep, sneeuw)

• Chat between sender and courier

• Order info includes address, selected products, and payment method (Tikkie, Cash, Pof)

• Stock decreases automatically after delivery

• Courier earns per product

• Low-stock warning system (if any item is 3 or less)

What I need you to do:

1. Hide stock counts in the order screen (only visible for sender)

2. Improve the chat interface so it looks more like a real conversation

3. Allow live updating of chat (same screen for sender and courier)

4. Reset order fields (address, product selection) after each order

5. Optional: Connect to Firebase or a local backend to store messages, users, inventory

6. Suggest and implement small improvements to make the app faster and easier to use

Important:

• This is for personal use only, not a public platform

• The app must stay lightweight, clean, and local-first

• If backend is added, it should be simple and optional (Firebase or Express.js)

• Code must stay readable and maintainable

Deliverables:

• Updated React Native code (preferably with Expo)

• If backend is used: setup instructions + minimal hosting

• Optional UI improvements (color, spacing, feedback)

Let me know how long you’d need and send me examples of your previous React Native or small mobile projects.
