My Role: Lead Backend Engineer
The crypto market never sleeps. To succeed in this environment, a platform must be fast, stable, and above all, secure. Vortex was built from the ground up to challenge the current leaders in the space by providing a superior trading experience for both retail and institutional clients.
The heart of Vortex is its matching engine. Written in C++ and integrated with our Node.js API layer via shared memory, it can handle over 1 million orders per second per pair. This ensures that even during periods of extreme market volatility, orders are filled instantly with zero lag.
Security is handled in layers. The frontend utilizes Hardware Security Module (HSM) integration for high-value accounts. On the backend, we use a custom-built Cold Storage Service that keeps 98% of assets offline, requiring multi-sig physical approval for any large transfers.
For professional traders, live data is everything. We implemented a Cluster-based WebSocket system that streams the order book and trade history with a p99 latency of under 5ms globally, using a custom binary protocol to minimize packet size.
Instead of using generic libraries, we developed a high-performance Canvas-based charting engine. This allows users to render hundreds of indicators and thousands of data points smoothly, even on low-end hardware.
Vortex was built with compliance in mind. We integrated automated KYC/AML workflows that verify user identities in over 190 countries within seconds, using AI to detect fraudulent documents and activity.
Since its launch, Vortex has facilitated over $50 Billion in total trading volume and maintains a 99.999% system uptime, becoming a trusted platform for some of the world's largest crypto hedge funds.
