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.

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.
