Next-Gen Investment Portal for Retail Traders

TradeFlow's existing mobile and web app was suffering from performance bottlenecks during market volatility. Users experienced lag, leading to lost trades and churn. They needed a complete re-architecture of their frontend to handle real-time data at scale.

We engineered a new high-performance web application using Next.js and WebSockets, optimized for sub-millisecond updates. We implemented a custom state management layer to handle the firehose of market data efficiently without freezing the UI. The design was overhauled to provide a pro-level trading experience with customizable layouts and advanced charting capabilities, comparable to institutional terminals.

The new platform supports 5x the concurrent user load with zero latency issues. User retention increased by 40%, and the app has maintained a 4.9-star rating across all platforms.
