High-performance Node.js backends for APIs, microservices, and real-time applications.
We build production-grade Node.js backends using NestJS, Express, and Fastify. Our engineers specialize in RESTful APIs, GraphQL servers, WebSocket applications, message queue consumers, and microservice architectures. We follow TypeScript-first development with comprehensive testing, structured logging, and performance optimization.
For new projects, we typically recommend NestJS for its modular architecture, dependency injection, and built-in support for microservices. For simpler APIs, Express or Fastify can be more appropriate.
We profile with clinic.js, optimize event loop usage, implement connection pooling, use streaming for large payloads, and design for horizontal scaling.
Yes. We regularly take over and improve existing Node.js projects. We start with a code audit, address critical issues, and incrementally improve architecture.
