The Challenge
Nexus's existing collaboration tool was built on a polling architecture that couldn't handle more than 50 concurrent users per workspace without severe input lag and desync issues.
- Implementing operational transformation algorithms for conflict-free text editing.
- Scaling WebSocket connections horizontally.
- Building an accessible design system from scratch.
Architecture & Solution
We engineered a robust real-time engine utilizing WebSockets and Redis pub/sub to handle state synchronization. The frontend was rebuilt using a custom React design system tokenized in Figma for ultimate consistency.
A Next.js frontend handles SSR for SEO-critical marketing pages, while the core app is a heavily optimized SPA. The backend utilizes a scalable cluster of Node.js WebSocket servers orchestrated via Kubernetes.
Business Impact
Key Outcomes
- Scaled successfully to support 10,000+ concurrent users.
- Increased Enterprise contract acquisition by 45%.
- Reduced customer support tickets related to sync issues by 95%.
Performance Metrics
- Sub-50ms real-time latency globally
- Zero dropped WebSocket connections under load
- 100/100 Lighthouse Accessibility Score
