FinTech Dashboard
Real-time analytics dashboard for a crypto trading platform with millisecond latency updates and complex data visualization.
Overview & Challenge
Tasked with building a performant UI for high-frequency traders, we utilized raw WebSockets for real-time market data streaming and D3.js for rendering complex order book charts. We optimized React rendering extensively to match the speed of the underlying websocket stream, resolving extreme UI freezing and drastically lowering terminal memory usage.
The Solution
To address the scaling and usability challenges, we engineered a robust infrastructure using modern web technologies. Focus was placed heavily on immediate feedback during user interactions and graceful edge-case handling.
