Service Overview

SoftwareCrafting builds real-time and messaging systems for products where users need instant state changes, live dashboards, chat, tracking, notifications, or background processing. We design Socket.io, WebSockets, server-sent events, Kafka, RabbitMQ, BullMQ, Firebase, Pusher, Redis streams, retry policies, dead-letter queues, presence, fan-out, and consumer scaling. We keep the architecture practical so your product gets low-latency updates without fragile connections or lost events.

Our Delivery Process

We use an agile, transparent process to ensure your project is completed on time and meets exactly your needs.

01

Event and latency mapping

We identify which product events must be instant, which can be queued, expected traffic patterns, ordering needs, fan-out, and delivery guarantees.

2-4 days
02

Messaging architecture

We choose WebSockets, SSE, Kafka, RabbitMQ, BullMQ, Firebase, or Pusher, then design topics, queues, retries, scaling, and observability.

3-5 days
03

Implementation and integration

We implement live APIs, background workers, event persistence, reconnection states, dead-letter queues, and user-facing real-time UI.

1-3 weeks
04

Load testing and monitoring

We validate throughput, reconnection behavior, message loss, queue depth, worker scaling, and alerting before launch.

2-5 days
Why Us

Why Choose SoftwareCrafting?

  • Live user experiences without constant polling
  • Reliable event delivery for queues, notifications, and workflows
  • Systems that handle traffic spikes without dropping messages
  • Better separation between product services through events
  • Clear monitoring for queue depth, failures, retries, and latency
  • Room to scale from simple WebSockets to event streaming when needed
FAQ

Frequently Asked Questions

Should we use WebSockets or server-sent events?
Use WebSockets when the client and server both need to send frequent messages, such as chat or collaboration. SSE is simpler for one-way live updates like dashboards, status feeds, and notifications.
Should I use Kafka or RabbitMQ?
Kafka is strong for high-throughput event streams, replay, audit logs, and analytics. RabbitMQ is usually better for task queues, routing, and work that needs explicit acknowledgement.
Can you add real-time features to an existing app?
Yes. We can introduce Socket.io, SSE, Firebase, Pusher, or a queue-based worker layer without rewriting your whole backend.
How do you prevent lost messages?
We use acknowledgements, durable queues, event logs, retries, idempotent consumers, dead-letter queues, and monitoring so failures are visible and recoverable.
