Hire Node.js Developers
Node.js is our primary runtime for backend services that demand real-time performance, high concurrency, and rapid iteration. We use it for REST and GraphQL APIs, WebSocket-based real-time apps, microservice backends, serverless functions on AWS Lambda, and data-processing pipelines. Our Node.js codebase is written in TypeScript with strict typing, comprehensive test coverage, and production-ready observability. From Chatify's real-time messaging engine to custom Shopify app backends, our Node.js developers build backends that handle millions of events without breaking a sweat.

Frequently Asked Questions
Node.js or Python: when do you recommend Node.js?
Node.js excels at real-time applications, high-concurrency I/O, and full-stack JavaScript ecosystems. We recommend it for APIs, WebSocket apps, and serverless backends.
Do you write tests for Node.js backends?
Yes. Every API we build includes unit tests with Vitest, integration tests with Supertest, and end-to-end tests where appropriate. We target 80%+ coverage.
Can you optimize an existing slow Node.js API?
Yes. We perform profiling with clinic.js, identify N+1 queries, add Redis caching, optimize database indexing, and refactor synchronous bottlenecks to async patterns.
