What is Node.js used for?

Node.js is the primary backend runtime for JavaScript and TypeScript teams — used for REST and GraphQL APIs, microservices, real-time applications, CLI tools, and serverless functions. It's the most common backend choice when the frontend is already in React or Vue.

Do your Node.js developers know NestJS?

Many Node.js specialists in our network have NestJS production experience. We filter by framework during intake — tell us whether you need Express, NestJS, or Fastify and we match accordingly.

How do you vet Node.js developers?

Candidates complete a timed API exercise and a system design interview covering the event loop, async patterns, database design, and scalability. Graded reports and coding recordings are shared before you talk to anyone.

How long does it take to hire a Node.js developer?

First candidate profiles arrive within 7 days. Full placement typically takes 2–3 weeks.

What is the cost of a Node.js developer from Latin America?

Senior Node.js developers from Latin America cost 30–50% less than US equivalents. Contact us for a custom quote.

What is Node.js and why do companies need Node.js developers?

Node.js is still the dominant backend for JavaScript-first teams — and for good reason. The event loop handles high-concurrency I/O workloads efficiently, startup time is fast enough for serverless, and sharing types across the full stack removes an entire category of bugs. But the gap between a developer who knows Node.js and one who actually understands the event loop, async error propagation, and memory management is significant. NeuronHire places Node.js developers from LATAM vetted on Express, NestJS, production API design, and async patterns under real load. Placed in 7 days, at 30–50% below US rates.

Built with Node.js

What companies build with Node.js

REST and GraphQL APIs

Node.js is the default backend for JavaScript teams because it eliminates the context switch between frontend and backend. Shared types, shared validation libraries, shared team knowledge — that's a real productivity advantage when you're moving fast.

Real-time applications

Node's non-blocking event loop was designed for exactly this: WebSocket connections, live dashboards, collaborative editing, and gaming backends where you're managing thousands of concurrent connections without a thread-per-connection overhead.

Microservices and serverless

Node.js cold starts in milliseconds and its memory footprint is small — which makes it the default runtime for AWS Lambda and containerized microservices where you're paying per invocation or per GB-hour.

Node.js interview questions

Junior

01Explain the Node.js event loop. What happens when you call setTimeout with a 0ms delay inside a Promise chain?
02What is the difference between require() and ES module import in Node.js? What problems can mixing them cause?
03How do you handle errors in an async/await function, and what happens if you forget to catch a rejected promise?

Mid-level

01You're seeing a memory leak in a long-running Node.js process. Walk me through how you'd diagnose it — what tools, what metrics, what you'd look for.
02Design a rate-limited job queue in Node.js that processes webhook events from a third-party API, handles retries with backoff, and guarantees at-least-once delivery.
03How does Node.js handle CPU-intensive work, and what are your options when you have a task that would block the event loop for 500ms?

Senior

01Design the backend architecture for a real-time collaborative document editor serving 100,000 concurrent users. Where does Node.js fit, what are its limits, and what else do you need?
02A Node.js API is consistently timing out under load even though individual queries look fast. Walk me through your full investigation — from first alert to root cause.
03How would you structure a large NestJS codebase across a team of 20 engineers, including module boundaries, shared services, testing strategy, and deployment?
