What It Does

  • Powers a collaborative project management platform centered around a shared digital whiteboard.
  • Coordinates real-time board interactions using WebSockets while ensuring persistence through queue-backed processing.
  • Connects external services for cloud file management and calendar/event synchronization.

Architecture Highlights

  • Winter CMS backend exposes collaborative APIs and orchestrates real-time events.
  • WebSocket channels deliver low-latency multi-user state synchronization on whiteboards.
  • Queue workers decouple persistence and heavy jobs to handle concurrent traffic safely.
  • Container pattern improves maintainability by isolating element-specific business logic.
