The challenge
Traders needed real-time prices and dependable order execution, and admins needed full control, all on top of a third-party exchange API.
What we built
Exchange integration
A live exchange API connected for market data, order execution and wallet operations.
Roles and security
JWT authentication with separate trader and admin roles.
Trading data
A MySQL schema for trade history and balances.
Fast prices
Redis price caching for quick reads.
Engineering decisions
- Cache-first price reads to protect third-party API rate limits.
- Role-based access enforced at the API layer, not just in the interface.
The result
A secure, role-aware trading backend that gives traders live data and admins control.
