The challenge

Teams needed to chat, meet over video, and sketch on shared whiteboards together — without lag and without edits colliding. Real-time collaboration is deceptively hard: presence, message ordering, and conflict-free editing all have to stay consistent across many concurrent users at once.

The solution

We built a real-time platform on high-performance backend services, with live video and a whiteboard whose edits merge automatically no matter who is typing or drawing. The architecture keeps everyone's view consistent in real time while staying responsive under load.

Architecture

• High-performance backend services in Go and Rust for low-latency messaging and presence.
• WebRTC-based video and audio for live meetings.
• Conflict-free (CRDT-style) sync so simultaneous edits on shared whiteboards merge without overwrites.
• Presence and pub/sub layer that scales to many concurrent sessions.
