Node.js Backend & API Development

Event-Driven Backends That Scale

Node.js is an open-source, cross-platform JavaScript runtime designed for scaling data-intensive, event-driven network applications. We write fast Express and NestJS backends on Node.js — with full TypeScript typing, structured error handling, OpenAPI documentation, and comprehensive integration test suites. Node's non-blocking I/O model means that a single server thread can efficiently handle thousands of concurrent connections without spawning a new thread per request, keeping memory consumption predictable under load. We use NestJS for larger enterprise APIs that benefit from its dependency injection container and modular architecture, and lightweight Express for microservices where minimal overhead is the priority. Every API we ship includes rate-limiting middleware, structured JSON logging, and health-check endpoints for container orchestration readiness probes.
