Pulse — a real-time data-visualisation layer for a trading platform

Ten thousand data points a second, rendered without dropping a frame. We rebuilt the platform’s entire chart layer on a custom WebGL renderer after the off-the-shelf charting library couldn’t hold 60fps past a few hundred concurrent series.

Scope: custom rendering engine, real-time data pipeline, design system.
Result: render time down 94%, zero dropped frames at full load.
