Real-Time System Development
Live data when milliseconds matter - WebSockets, pub/sub, and streaming pipelines for chat, notifications, collaboration, and live dashboards.
Trusted by companies that ship production software on deadline
Everything you need, nothing you don't
We scope each engagement precisely so you get senior-level work on the capabilities that matter.
WebSocket servers
Persistent bidirectional connections for chat, live updates, and gaming - with heartbeat, reconnection, and horizontal scaling via sticky sessions or pub/sub.
Server-Sent Events
One-way streaming over HTTP for notifications, feed updates, and progress bars - simpler than WebSockets when clients only need to receive.
Pub/sub messaging
Redis or Kafka-backed fanout so events reach every connected client - decoupling publishers from subscribers at scale.
Presence indicators
Online/offline status, typing indicators, and last-seen timestamps - synced across tabs and devices with efficient heartbeat protocols.
Live collaboration
Multi-user editing, shared cursors, and conflict resolution - so teams work together in real time without overwriting each other.
Streaming analytics
Windowed aggregations and live metric pipelines - feeding dashboards and alerts as events arrive, not after batch jobs finish.
From latency requirements to live features
We define your real-time SLA first, then choose the right transport and scaling strategy before shipping features incrementally.

Week 1: Real-time architecture & SLA
We map latency requirements, connection volumes, and failover needs - then choose WebSockets, SSE, or hybrid patterns for each use case.

Weeks 2-8: Build & load test
Connection handlers, pub/sub backends, and client SDKs ship incrementally - each sprint includes load testing against your target concurrency.

Launch: Scale & monitor
We deploy with auto-scaling, connection metrics, and alerting - plus documentation for your team to extend real-time features post-launch.
Renting is local, so search had to understand a place and a date range as one question rather than two filters. Mirimera built the marketplace and the software our suppliers run on, and because it is one system underneath, nothing has ever had to be kept in sync.

CEO, Big RentalsReal-time stack we ship
Low-latency messaging and streaming tools - chosen for connection reliability, horizontal scale, and sub-second delivery guarantees.
Socket.io
WebSocket library with automatic fallback, rooms, and namespaces for chat, notifications, and live updates.
Redis Pub/Sub
In-memory pub/sub for fanout across server instances - with optional persistence for presence and session state.
Apache Kafka
Durable event log for streaming analytics, replay, and high-throughput pipelines feeding live dashboards.
- gRPC
gRPC
Binary RPC for low-latency service-to-service calls in streaming and bidirectional communication patterns.
- Ab
Ably
Managed real-time infrastructure for global pub/sub, presence, and message history without operating your own cluster.
Node.js
Event-driven runtime for concurrent WebSocket connections and async I/O at the heart of real-time backends.
