High-performance REST and GraphQL APIs, real-time services and microservices architectures — built with Node.js for the speed and scale your product demands.
Well-structured, documented APIs with authentication, rate limiting, validation and consistent error handling — built to integrate cleanly with any frontend.
🔄
Real-Time Applications
WebSocket and Server-Sent Events for live notifications, collaborative tools, dashboards and chat — socket.io or native WS with Redis pub/sub.
🏗️
Microservices Architecture
Event-driven services with RabbitMQ or Kafka message queues, service discovery and circuit breakers — modular systems that scale independently.
🗄️
Database Engineering
MongoDB, PostgreSQL or MySQL with Mongoose/Prisma ORM, connection pooling, query optimisation and automated migration strategies.
🔐
Auth & Security
JWT and OAuth 2.0 authentication, RBAC, input sanitisation, helmet.js headers and rate limiting — security that doesn't slow you down.
🚀
Performance & Scaling
Cluster mode, worker threads, Redis caching, horizontal pod scaling on Kubernetes — Node.js backends that handle thousands of concurrent connections.
Why Cognigain Tech
What sets us apart.
✓
Senior engineers, not juniorsYour project is handled by developers with 4+ years of Node.js production experience — not freshers learning on your dime.
✓
Performance-engineeredWe profile, benchmark and optimise from day one — async patterns, connection pooling and caching mean your API stays fast under load.
✓
Thorough documentationEvery API is documented with Swagger/OpenAPI — your team and future developers will never be guessing about endpoints.
✓
Test coverage from day oneUnit tests with Jest, integration tests with Supertest and CI pipelines that catch regressions before they reach production.
✓
Microservices-readyWe architect for the future — services that can be split, containerised and scaled independently as your product grows.
✓
Transparent communicationFortnightly demos, a shared project board and Slack/WhatsApp access — no black-box development cycles.
