Large Datasets, Still Sixty

Battery telemetry arrives in volumes that make naive charting hostile. Every interaction — a brush, a zoom, a filter — triggered computation that blocked the interface.

I engineered a high-performance React SPA with real-time interactive visualisations in Recharts and Highcharts, offloading heavy computation to Web Workers so the UI stays responsive over datasets that would otherwise stall it.

Multi-file upload ships with live progress tracking, and the dashboard itself is shareable and authenticated, with guided onboarding for first-time users.

Filtering and exploring large datasets stays interactive rather than becoming a request-and-wait cycle.
