Observa Dashboard
Real-Time Enterprise Data Visualization Platform
A high-performance real-time data visualization dashboard built with React 19 and Next.js 15, featuring custom WebGL shaders, live data streaming via SignalR, and enterprise-grade accessibility compliance.
The Challenge
Enterprise teams needed a real-time analytics dashboard capable of visualizing 50,000+ data points per second with sub-100ms refresh rates, while maintaining full WCAG 2.1 AA accessibility compliance and offline-first capabilities.
Our Solution
We built a Next.js 15 application with React 19, leveraging SignalR with MessagePack serialization for real-time data streaming. Custom D3.js and WebGL shaders handle complex data visualizations at 60fps. Zustand manages client state, TanStack Query handles server state with optimistic updates, and Web Workers offload heavy computations to prevent UI blocking. IndexedDB provides offline storage with Service Worker caching.
The Results
The dashboard renders 50K+ data points per second with consistent sub-100ms latency. Playwright e2e tests and Vitest unit tests ensure reliability. Lighthouse scores consistently hit 95+ across all categories, and the platform meets full WCAG 2.1 AA compliance for enterprise accessibility requirements.
