Ryngr

Ryngr needed a real-time messaging foundation that stays stable under load while maintaining a crisp user experience across devices. The product required reliable delivery semantics, presence signals, and a clean UX that doesn’t degrade when networks are unstable.

Messaging systems become fragile quickly without the right event model, observability, and infrastructure readiness.

We designed a scalable event-driven architecture with WebSockets for real-time communication and queue-backed processes for reliable fan-out and background work.

The UX was built around clear state transitions: connecting, online/offline, delivery, and read states — reducing confusion and improving perceived speed.

• WebSocket layer for low-latency delivery and presence.
• Queue-backed events for resilient processing and fan-out.
• Redis for ephemeral state and high-speed data structures.
• Horizontal scaling with stateless services and clear boundaries.

• Real-time messaging with delivery and read states.
• Presence, typing indicators, and multi-device readiness.
• Media sharing with safe upload flows.
• Monitoring hooks to catch issues before users do.
