The Challenge

The client needed a platform capable of handling $2M+ in daily transactions while maintaining sub-second latency and zero-trust security architecture. The existing legacy system suffered from frequent timeouts and lacked real-time audit logging, making it vulnerable to sync errors during high-volatility market periods.

The Solution

We implemented a microservices architecture using Node.js and Redis for caching, combined with a React-based frontend for real-time data visualization. We utilized WebSocket protocols for live market updates and integrated a custom AES-256 encryption layer for all sensitive transaction data. The system was deployed on an auto-scaling AWS infrastructure to ensure 99.9% uptime during peak loads.
