Node.js Development
Node.js backends
Node.js backends
built to scale
at any size.
From MVP APIs to high-throughput enterprise backends — Cognigain Tech engineers Node.js systems that are fast, secure, well-documented and production-hardened from day one.
What We Deliver
Core capabilities we offer.
Purpose-built solutions, not generic templates.
REST API Development
Clean, versioned RESTful APIs with OpenAPI documentation, rate limiting, authentication and comprehensive error handling — built to be consumed by any frontend or third-party system.
GraphQL APIs
Type-safe GraphQL schemas with Apollo Server, efficient resolvers, DataLoader for N+1 prevention and subscriptions for real-time data — ideal for complex data requirements.
Real-time Applications
WebSocket and Socket.io based real-time features — live dashboards, collaborative tools, notifications and chat systems with Redis-backed pub/sub.
Database Integration
Production-grade integrations with MongoDB (Mongoose), PostgreSQL (Prisma/Sequelize), Redis and Elasticsearch — with migrations, indexing and query optimisation.
Authentication & Security
JWT, OAuth2, Passport.js, bcrypt password hashing, CORS configuration, helmet.js security headers and RBAC — security as a first-class requirement.
Cloud Deployment & DevOps
Node.js applications deployed on AWS EC2/ECS, containerised with Docker, managed with PM2, and served through Nginx reverse proxy with auto-scaling and zero-downtime deployments.
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.
