From transit operations centers and IoT fleet monitors to algorithmic trading desks and live collaborative workspaces, decision-makers need real-time dashboards that stream thousands of state changes per second without freezing the browser or overloading backend databases.
If you are looking to hire a freelance real-time dashboard and WebSockets programmer, I am Aldian Fazrihady—a senior full stack engineer who has built public real-time transit simulators (MRT Jakarta Traffic Simulation), WebSocket chat systems, and high-frequency telemetry dashboards.
Engineering High-Throughput Real-Time Dashboards
1. Scalable WebSocket & SSE Fan-Out Backends
Using Go (Gorilla/nhooyr WebSocket), Python (Django Channels / FastAPI ASGI), and Redis Pub/Sub or NATS, I design horizontally scalable fan-out servers that push delta-compressed state updates to tens of thousands of connected browsers with sub-50ms latency.
2. 60fps React Rendering with RequestAnimationFrame Batching
Triggering a React state re-render on every incoming WebSocket packet will lock up the main thread when 200 messages arrive per second. I buffer incoming messages in a mutable ring buffer and flush coalesced UI updates on a requestAnimationFrame or 100ms tick, pairing virtualized tables with HTML5 Canvas/WebGL charts.
3. Automatic Reconnection & Gapless State Recovery
Mobile and office networks drop connections constantly. I implement exponential backoff reconnection with sequence-ID cursors so clients seamlessly replay missed events upon reconnecting without full-page reloads.
