The brief

Track multi-asset positions in real time without frame drops.

What I built

A WebSocket-driven portfolio dashboard with canvas-rendered live charts.

What it shows

The chart layer renders off the React tree entirely — a direct-to-canvas draw loop keyed to the WebSocket feed, so 500+ updating points never trigger a component re-render.
