Problem
Distributed fleet deployments generate millions of system log lines and telemetry events per minute. Operators required sub-second incident diagnostics, but existing dashboards choked on DOM overhead when streaming more than a few hundred rows concurrently.
Role
Staff frontend engineer leading client performance architecture and realtime visualization modules.
Architecture & Stack
- Canvas Stream Virtualization: Custom rendering engine virtualizing 50,000+ tabular records and charts with steady 60fps scrolling and memory pooling.
- WebSocket Chunk Multiplexing: Compressed binary telemetry chunks decoded on Web Workers to prevent UI thread starvation.
- ClickHouse Analytical Queries: Optimized parameterized analytical aggregates delivering query results in under 50ms.
Outcome & Metrics
- Sustained 40,000 events/second live ingestion with zero browser tab crashes or memory leaks.
- Lighthouse performance and Core Web Vitals score improved from 58 to 98+.
- Reduced client-side JavaScript bundle footprint by 54%.
