Node.js Backends, Built for Scale

From REST APIs to real-time WebSocket services, our AI-managed teams deliver production-grade Node.js backends with TypeScript and milestone-based delivery.

Technology: Node.js (Backend Runtime)

Node.js powers our backend services with its event-driven, non-blocking architecture ideal for real-time applications and high-throughput APIs. Combined with TypeScript, it delivers the performance and developer experience needed for modern web applications. Our teams build everything from REST APIs to real-time WebSocket servers on Node.js.

What We Build

  • REST & GraphQL APIs: Scalable API backends with authentication, authorization, rate limiting, and comprehensive documentation.
  • Real-Time Applications: Chat systems, live dashboards, collaborative editors, and notification services using WebSockets and Server-Sent Events.
  • Microservices: Independently deployable services with event-driven communication, service discovery, and centralized logging.
  • Backend for Mobile & Web Apps: Full backend systems with user management, file uploads, payment processing, and third-party integrations.

Expertise

  • Node.js Backends Delivered: 250+
  • Average API Response Time: Under 100ms
  • Uptime for Deployed Services: 99.9%

Frequently Asked Questions

Do you use Express, Fastify, or NestJS?
We choose the framework based on project needs. NestJS for complex enterprise backends, Fastify for high-performance APIs, and Express for simpler services. All projects use TypeScript.
Can Node.js handle enterprise-scale traffic?
Absolutely. Node.js powers Netflix, PayPal, and LinkedIn at massive scale. With proper architecture (clustering, caching, horizontal scaling), Node.js handles millions of concurrent connections.
Do you include database setup with Node.js backends?
Yes. Every backend project includes database design, ORM setup (Prisma or TypeORM), migrations, and seeding. We typically pair Node.js with PostgreSQL or MongoDB depending on your data model.
