Node.js Development Company
Scalable APIs and real-time backends
We build Node.js backends that handle thousands of concurrent connections and process millions of API requests daily. Our team has shipped 60+ Node.js applications — from REST APIs serving 50M+ requests/month to WebSocket servers powering real-time collaboration for 10K+ simultaneous users. We work with Express, NestJS, and Fastify depending on project requirements. Need dedicated talent?

What sets our node.js development apart
High-Throughput APIs
Non-blocking I/O makes Node.js ideal for API servers. We build REST and GraphQL APIs that handle 10K+ requests/second on standard infrastructure.
Microservices Architecture
We design and implement microservices with message queues (RabbitMQ, Redis Streams), service discovery, and circuit breakers for fault-tolerant distributed systems.
Real-Time Communication
WebSocket and Socket.io implementations for chat, notifications, live dashboards, and collaborative editing. Connection management for 10K+ concurrent users.
TypeScript Backend
Every Node.js project uses TypeScript for type safety across the stack. NestJS for enterprise patterns or Express/Fastify for lean APIs — always type-safe.
Database Optimization
PostgreSQL, MongoDB, Redis, and DynamoDB expertise. We design schemas, write efficient queries, set up connection pooling, and implement caching layers.

Common questions about node.js development
When should I choose Node.js over Python or Java for my backend?
Node.js excels at I/O-heavy workloads: APIs, real-time features, and microservices. Python is better for ML/data processing, and Java for CPU-heavy enterprise systems. If your stack is JavaScript/TypeScript on the frontend, Node.js gives you full-stack type sharing.
Can Node.js handle enterprise-scale applications?
Yes. Companies like Netflix, LinkedIn, and PayPal run Node.js in production at massive scale. We use NestJS for enterprise patterns — dependency injection, modular architecture, and built-in testing. Proper architecture and horizontal scaling make Node.js production-ready for any load.
How do you handle Node.js security?
We implement helmet.js for HTTP headers, rate limiting, input validation with Zod, parameterized queries to prevent SQL injection, JWT with rotation for auth, and dependency auditing with npm audit in CI. Every API endpoint gets input sanitization and output encoding.
What does Node.js API development cost?
A standard REST API with authentication and CRUD operations costs $10,000-$25,000. A microservices backend with message queues, caching, and real-time features ranges from $30,000-$80,000. We provide detailed breakdowns after requirements gathering.
Do you provide Node.js maintenance and monitoring?
Yes. We set up PM2 or Docker orchestration, application performance monitoring with Datadog or New Relic, structured logging with Winston, and alerting for error rates and response times. Ongoing maintenance is available on monthly retainer.
How much does it cost to hire a dedicated Node.js developer?
Dedicated Node.js developers cost $1,500-$2,500/month for junior, $2,500-$4,000/month for mid-level, and $4,000-$6,500/month for senior engineers. NestJS specialists command a 10% premium. Full-time, 160 hours/month with all overhead included. Equivalent US Node.js developers cost $9,000-$14,000/month.
Node.js vs Python — which backend should I build?
Node.js for I/O-heavy APIs, real-time features, and full-stack TypeScript. Python for AI/ML integration, data processing, and scientific computing. Node.js handles 10K+ concurrent connections efficiently. Python has stronger ML libraries. For a SaaS backend without ML, Node.js saves 15-20% in development time due to shared frontend types.
Can you build a custom Node.js API for my food delivery app?
Yes. We built a food delivery marketplace handling 15K+ daily orders with real-time tracking, payment processing, and driver assignment. A Node.js backend for a delivery platform costs $30,000-$80,000 depending on features. Get a dedicated Node.js developer from $2,500/month to start building in 1 week.
