Development - Real-Time Applications

Some applications need to react the moment something happens. I build real-time features and full real-time applications — live chat, collaborative editing, real-time notifications, live dashboards, and multiplayer experiences. Powered by WebSockets, Server-Sent Events, and event-driven architecture that handles thousands of concurrent connections without breaking a sweat.

What's included

Every real-time applications engagement includes these core capabilities — tailored to your specific requirements.

WebSocket-based real-time communication infrastructure

Live chat and messaging systems with typing indicators

Collaborative editing (Google Docs-style) with conflict resolution

Real-time notification systems with delivery guarantees

Live dashboards with streaming data visualizations

Presence detection — who's online, who's typing, who's viewing

Event-driven microservice communication with message queues

Horizontal scaling with Redis pub/sub for multi-server deployments

How it works

A structured, transparent process from initial requirements to production deployment.

01

Requirements & Architecture

I define what needs to be real-time and what doesn't, then design an event-driven architecture that handles your expected scale without over-engineering.

02

Infrastructure Setup

I set up WebSocket servers, message brokers, and Redis pub/sub — with proper connection management, reconnection logic, and graceful degradation.

03

Feature Development

I build the real-time features into your application layer by layer — messaging, presence, notifications, live updates — each tested under concurrent load.

04

Load Testing & Deployment

I stress-test with thousands of simulated connections, optimize for latency, and deploy with auto-scaling so your real-time features hold up at peak traffic.
