Overview
In this 12-hour live coding session, I built and deployed a full-stack virtual crypto exchange app using React Native and AWS Amplify. The app allows users to invest virtual money in cryptocurrencies, compete on a global leaderboard, and learn risk-free trading strategies—all while leveraging modern development tools.
Key Features
- Virtual Crypto Exchange: Simulate real-world trading without financial risk.
- Leaderboard Integration: Compete with other users globally.
- Tech Stack: React Native (Expo SDK), AWS Amplify (GraphQL backend).
Development Workflow
1. Project Setup
- Initialized a React Native project using Expo SDK.
- Structured the app with reusable components and modular design.
2. UI/UX Design
- Implemented responsive layouts for trading screens and portfolios.
- Added React Navigation for seamless tab bars, headers, and screen transitions.
3. Backend Integration
AWS Amplify Services:
- Authentication: Pre-built user sign-up/log-in flows.
- Database: Managed data via GraphQL API.
- Storage: Handled transaction history and user profiles.
Why This Approach?
- Speed to Market: Amplify’s pre-configured services accelerated deployment.
- Scalability: GraphQL ensures efficient data fetching for real-time trading updates.
FAQs
Q: Can I use real money in this app?

Q: How do I deploy my own version?
A: Fork the GitHub repo and follow the AWS Amplify setup guide.
Q: Is React Native suitable for high-frequency trading apps?
A: For real-time virtual trading, React Native works well. For actual crypto exchanges, consider native solutions for ultra-low latency.
