Hire Node.js Developers for APIs, jobs and real-time work
Node.js developers already employed on our team in India, working hours that face New York. You interview the developer before signing, work starts within 24 hours of signing, and every commit lands in a repository held in your name.
On this page
To hire a Node.js developer from Digital Heroes, tell us what the service does and what it connects to, interview the developer we put forward, then sign. The developer starts within 24 hours of the signature, in practice the next working day, and is already on our team in India. They work in your repository on hours that face New York, and what they write for you is assigned to you on full payment.
What arrives when you hire one of our Node.js developers
The developer you interview is the one who writes your code. They were on our payroll before you called, not sourced from a marketplace after you paid, and they join your standups, take tickets from your board and open pull requests against your repository like anyone else on your team. If the interview goes badly, say so then, before anything is signed.
A backend is rarely only a backend. One that takes payments needs someone who knows the provider's webhooks; one that feeds a phone app needs an API agreed with whoever builds the app. The developer has colleagues for both sides: React and Next.js on the web, React Native, Flutter, Swift and Kotlin on mobile, and Python for data work, all on the same team.
What comes with the developer
| Included | Why it matters to you |
|---|---|
| A developer we employ | Already on our staff, writing Node.js in TypeScript or plain JavaScript to match the codebase you already have |
| Your interview first | Put your questions, and your own security checks, to the person who will write the code before anything is signed |
| A start within 24 hours | Day one is the next working day after you sign |
| A mutual NDA | One page, signed as soon as a scoping call is booked, ahead of any code or credentials changing hands |
| Accounts in your name | The repository, the npm organization, the cloud accounts and the CI secrets stay yours; the developer is added as a member and removed in one step |
| A senior standard behind them | Our CTO decides who joins the engineering team and the bar they are held to |
What Node.js developers build, and when to pick another runtime
Node.js runs JavaScript on the server, and it is at its best when a process spends most of its time waiting: on a database, on a payment provider, on a client holding a connection open. Your code runs on one main thread, the event loop, while slow input and output is handed to the operating system and a small pool of worker threads. One process can keep many waiting requests moving at once.
| The work | What the developer builds | Tools you will hear |
|---|---|---|
| APIs for web and mobile apps | REST or GraphQL endpoints with sign in, input validation and rate limits | Express, Fastify, NestJS |
| Payments and webhooks | Handlers that confirm who sent a notification, and check its signature, before an order or subscription changes | Stripe, PayFast and other provider SDKs |
| Background jobs | Queues for email, imports, file processing and retries that must survive a restart | BullMQ on Redis, cloud queues |
| Real-time features | Chat, live dashboards and notifications over connections that stay open | WebSockets, Server-Sent Events |
| Server code beside a web app | Route handlers and server actions that live inside the same project as the pages | Next.js, React |
| Functions at the network edge | Small APIs and redirects that answer close to each caller | Cloudflare Workers, which provide a subset of the Node.js APIs |
The label is common; depth in a framework is not. In Stack Overflow's 2025 Developer Survey, 49.1 percent of professional developers said they had done extensive work in Node.js over the past year, against 20.3 percent for Express, 7.4 percent for NestJS and 3.1 percent for Fastify.
The survey does not separate running a server from running the build tools of a front-end project, which also need Node.js, so the headline share flatters the number of people who have kept a Node.js service alive. Read "Node.js" on a CV as a starting point, then ask which framework, which version, and what broke in production.
When another runtime fits better
- Machine learning, analytics or data cleaning: Python, which we also staff in-house. The libraries that work depends on, such as pandas, NumPy and PyTorch, are written for Python first, so a Node.js service would end up calling out to them anyway.
- A service that mostly computes rather than waits, such as video transcoding or a pricing engine run on every request: Go or Rust, which compile to machine code and spread one program across every core. In Node.js the same job means splitting it onto worker threads and managing them yourself.
- A system already running on PHP and Laravel: extend it rather than rewrite it. Laravel and PHP developers are on our team too, and a second backend language is a second hiring pool for you.
Three ways to bring us in, and who reviews the code
Pick the model by one question: who on your side can read a Node.js pull request and say no to it? If someone can, one developer inside your team is the cheapest way to more output. If nobody can, buy the review along with the code, through a dedicated team or a fixed-scope build where our lead answers for the result.
| Model | You get | Who reviews the code | Billing | It starts |
|---|---|---|---|---|
| Developer inside your team | One in-house Node.js developer in your repository, your sprints and your standups | Your own tech lead | Per engineer, per month | The next working day after signing |
| Dedicated team | A lead, several engineers and QA, responsible for one part of your product | Our lead, working from your roadmap | By the month, usually for at least a quarter | Once the team is put together |
| Fixed-scope backend build | Two weeks of discovery, billed separately, then a single price against a written scope | Our team, measured against the written scope | A fixed price agreed when discovery ends | When discovery begins |
The 24-hour start belongs to the first model. Putting a full team together takes longer, and how we staff one is set out on our dedicated development team page. If the backend is one part of a larger system you want built and handed over, our page on hiring a bespoke software house explains that route, and our custom API development page covers API work end to end.
The going rate for Node.js work, on three public sources
We do not publish a rate card. We price one developer by the month, and only after a call has settled the hours, the seniority you need and how much of your day the work must overlap. The figures below are public, so any quote, ours included, can be held against something other than a vendor's word.
| Source | Figure | What it measures |
|---|---|---|
| Upwork, Node.js developers | $18 to $38 an hour, median $25 | Past freelance contracts worldwide; Upwork notes the final rate is negotiated |
| Upwork, by level | Beginner $20 to $30+, intermediate $30 to $60+, expert $60 to $90+ an hour | Upwork's own grading, from setting up a server to building npm packages from scratch |
| GoodFirms 2026 survey | $20 to $50 an hour at 56.3 percent of firms | Software firms of every stack, mostly in Eastern Europe, Latin America and South and Southeast Asia |
| GoodFirms 2026 survey | $100 to $250 an hour | Where GoodFirms places enterprise work in the US, Canada and Western Europe |
| US Bureau of Labor Statistics | $135,980 a year, median | US software developers, May 2025; the lowest tenth earned under $82,460 and the highest tenth over $214,670 |
Put the salary on the same footing as the hourly bands and the gap narrows. Spread over 2,080 paid hours, the BLS median comes to about $65 an hour in wages alone, already inside the expert band Upwork reports for freelance Node.js work, and that is before benefits, payroll tax, a laptop or the weeks a search takes.
So compare routes on what the rate includes rather than on the rate. Ask who reviews the code, who is on call when the service falls over, and what happens to the work if the person leaves. A low hourly figure that includes none of those is a cheap hour, not a cheap backend.
Pricing a whole backend rather than a month of one developer is a different question. A focused first version of custom software typically costs $40,000 to $150,000, and complex enterprise platforms $250,000 to $500,000 or more; our custom software cost guide sets out what moves the figure.
To run this on your own hours, our free offshore development cost calculator prices one workload at offshore, nearshore, US mid-market and US senior rates, while the in-house vs agency cost calculator weighs an employee against an agency and a freelancer, with hiring and overhead counted.
Seven questions taken from a service in production
Each question below starts from something that goes wrong on a live service rather than from the language: a slowdown nobody can explain, one missed error that stops the process, a supplier that stops answering, a dependency nobody vetted. Listen for what the candidate checks first and what they leave out. Ask our developer the same seven you ask anyone else, then compare the answers side by side.
- "Every endpoint slows down at once, but only while one admin export runs. What is your first guess, and how do you prove it?" The export is probably doing heavy JavaScript work on the main thread, so every other request waits behind it (figure 1). A good candidate measures with
perf_hooks.monitorEventLoopDelay()ornode --cpu-profbefore moving the export to a worker thread or a separate job. The Node.js guide Don't Block the Event Loop explains why. - "Your API relays a long video to object storage, and storage takes bytes more slowly than the client sends them. Where do the extra bytes go?" You want to hear backpressure: reading only as fast as storage accepts, by honouring a
write()that returns false or by lettingpipeline()run the flow, which also tears down both sides if one fails. Holding chunks in memory until storage catches up is how the process runs out of it. - "An async route handler in Express 4 throws after an
await. What does the client get?" Express 4 ignores the promise a handler returns, so the error never reaches the error middleware: the client gets no response, and on Node.js 15 or later the unhandled rejection stops the process unless something catches it. Express 5 forwards a rejected promise to the error handler itself. Anyone who has upgraded a service, or wrapped handlers by hand, knows this. - "A supplier's API your route calls starts taking 40 seconds to answer. What happens to your service?" Without a deadline, requests queue behind the supplier while open sockets and memory pile up. Expect a timeout on every outbound call, such as
AbortSignal.timeout()passed tofetch, a cap on how many calls can wait at once, and a decision on what users see meanwhile: cached data, a queued retry or a clear error. - "Six replicas each keep a pool of 15 connections to a Postgres server capped at 100. What happens during a rolling deploy?" The steady state already uses 90. While old and new replicas overlap, up to 180 connections are asked for, and Postgres refuses the ones past its cap. A senior names the fix without prompting: smaller pools, a connection pooler such as PgBouncer, or a deploy that drains before it scales up.
- "How does a new npm package earn its place, and what do you do when an audit flags a critical advisory deep in your dependency tree?" Listen for a committed lockfile,
npm ciin the pipeline, pinned versions and telling an exploitable path from noise. CISA's September 2025 alert on the Shai-Hulud worm, which compromised over 500 npm packages and went after GitHub tokens and cloud keys, told organizations to review their dependencies and pin versions to known safe releases. - "Which Node.js version does your last production service run, and when does it stop getting fixes?" Per the Node.js release schedule, version 20 reached end of life on 30 April 2026, 22 is in maintenance until 30 April 2027, 24 moves to maintenance on 20 October 2026 and 26 becomes the long-term support line on 28 October 2026.
A take-home worth paying for
Ask the candidate to review code rather than write it. Open a pull request on a small Node.js service that looks finished but hides two problems: a database pool created inside the request handler, so every request opens new connections, and an unlimited retry loop around a payment call. First they leave written review comments; then, on a short call, they say which comment would block the merge and why. Budget about two hours, and pay for them.
Three things in a candidate's own sample code should end an interview early. A committed .env file, or API keys written straight into the source. TypeScript with strict mode switched off and any on most function signatures, which throws away the checking the language exists to give. And a project described only as "we", with no part the candidate can say they wrote, changed and would defend.
From signature to a change in production
The first working day after you sign is spent on access, not code, and anything the developer cannot open on that day is the first thing to slow the work. Four things are worth arranging before the signature: the repository, a staging environment, read access to logs and error tracking, and a way to share secrets that is not a chat message.
- Day 1, the service running locally. The developer runs the service and its test suite, reads the deploy pipeline end to end, and lists what is missing: environment variables, a seeded database, a sandbox account with your payment provider.
- Days 2 to 5, one small change in production. A small ticket goes through review, CI and staging to production. That run tests the whole route to release while the stakes are still small.
- Week 2, a real backlog item. Sized to be finished within the week, and covered by an integration test that runs against a real database, so it fails when the query does.
- Day 14, a short written report. Shipped work, the things that slowed it, and the risks spotted along the way: an unpinned dependency, a Node.js version close to end of life, a service with no shutdown handler.
This model rests on someone at your end reviewing the work. Without that reviewer, choose the dedicated team instead: our lead is accountable for the work, and internal QA checks every push before you see a preview.

Whose payroll the developer is on, and how to verify it
Our own staff cover Node.js, alongside Laravel and PHP, Angular, Magento, Python and four mobile stacks, so nobody is recruited once you have signed. No developer is named on this page. The person we put forward is someone you meet in the interview and judge on the questions above, not on a profile we wrote.
Engineering is based at our Delhi headquarters, where the backend, frontend, mobile, QA and DevOps teams sit. Lucknow adds full-stack developers, and some of our mobile engineers work from Sydney. Our CTO, Divyansh Singh, runs engineering and decides who joins the team and the standard they must meet. Node.js is part of his own stack, and his rule for generated code is that nothing goes in that the team cannot explain line by line.
You can check the company without asking us anything. On Clutch the rating is 5.0 from 66 verified reviews (checked 13 October 2026). Our DUNS number with Dun & Bradstreet is 650878346, and the UN Global Marketplace lists us as a Tier 1 supplier. Our entities and offices, and how to verify each, are on the custom software development company page.
Server-side JavaScript we can show, without results figures
SpeedyPrint is an online print store in South Africa, built by us in 2026 and shown with the client's permission. In its browser editor, customers lay out labels, race numbers, stamps and trophies, including CSV batches in which each item has its own name or number. Proofs and production files carry an order status history, and an admin panel serves three roles: customer, admin and production staff.
Its server side is Next.js 15 route handlers written in TypeScript, which run on Node.js, over a Supabase database. That layer takes PayFast checkout through payment webhooks and sends transactional email. The webhook is the part worth raising with any candidate: before an order changes status, the handler confirms the notification came from PayFast and that its signature matches. Skip either check and anyone can mark an order paid.
We run our own JavaScript in production too. The live chat assistant on this site is ours: its API runs on Cloudflare Workers and its conversations sit in PostgreSQL on Supabase, and the AI copilot in our own CRM is built in-house as well. Workers provide only a subset of the Node.js APIs, so a developer who has written for both knows which code moves between them and which does not.
None of these builds has a results figure we may publish, so none is given. What they show a hiring manager is the everyday shape of Node.js work: payments that must not be faked, email that must arrive, records that several roles see differently, and code that runs on more than one JavaScript runtime.
Hours, contracts and who owns the code
Engineers in Delhi and Lucknow set their working day to overlap New York's. Our New York office replies within the business day (9 AM to 6 PM Eastern, Monday to Friday). Outside those hours, Delhi and Sydney cover production emergencies at any time and answer an after-hours message within one to two hours.
Put the agreed overlap in the statement of work rather than in anyone's memory; our free time zone planner marks the hours your city shares with Delhi. The MSA states which company you sign with, either Digital Heroes Technologies Pvt Ltd in India or Digital Heroesco LLC in the US, and US engagements usually fall under New York law.
Once you have paid in full, the MSA assigns you everything made specifically for your project, the code included, while we keep the libraries and tooling we had before it began. If you need strict work-for-hire terms that also waive our portfolio rights, the SOW can say so, at a price stated up front. Where the service touches patient data, we sign a BAA whenever our team handles PHI.
For a Node.js service, ownership also means the accounts around the code. Keep the npm organization, the cloud accounts, the CI secrets and the payment provider's dashboard in your company's name, and give the developer scoped access you can revoke on the day the engagement ends. Require phishing-resistant multifactor sign in on their GitHub and npm accounts, which CISA urged on every developer account after the 2025 worm.
Questions buyers ask before they sign
How much does it cost to hire a Node.js developer?
Upwork puts the median for freelance Node.js work at $25 an hour, with most rates between $18 and $38 and experts at $60 to $90 or more. In GoodFirms' 2026 survey, 56.3 percent of software firms charge $20 to $50 an hour, while $100 to $250 is standard in the US, Canada and Western Europe. A US software developer at the BLS median earns $135,980 a year before benefits. We quote our own monthly rate after a call.
How soon can a developer start?
Inside 24 hours of the signature, so on the next working day. The time before that is mostly yours: a scoping call, the interview with the developer we propose, and the contract. A dedicated team takes longer to put together than one developer, while a fixed-scope build starts with a two-week discovery period.
Do I need a backend specialist or a full-stack engineer?
Count what sits behind the screens. If the backend is one database and a set of endpoints serving your own front end, a full-stack TypeScript engineer covers it, and one person owns each feature from button to table. When the backend talks to several outside systems, runs scheduled or queued jobs, or serves partners through a public API, give it someone who works only there. The interview questions are written for that second person.
What is the difference between Node.js and Express?
Node.js is the runtime that executes JavaScript outside a browser, with its own modules for files, networking and processes. Express is a web framework that runs on Node.js and handles routing and middleware for HTTP requests; Fastify and NestJS are alternatives on the same runtime. Someone can know Express well and still misunderstand the runtime beneath it, which is what an interview should test.
Can I pay by the hour or for a single project?
A developer embedded in your team is billed monthly, per engineer. Work with a clear finish line, such as one integration or a move from one framework to another, suits a fixed-scope build instead: two weeks of discovery, billed separately, end in a fixed price for a written scope or in advice that you need no build at all.
Is Node.js still a sound choice for a new backend?
For APIs, webhooks, queues and real-time features, yes. It topped the web technologies professional developers used in Stack Overflow's 2025 survey, at 49.1 percent, so a developer who leaves can be replaced. Its releases follow a published schedule: recent LTS lines get about 30 months of fixes, so budget for an upgrade every two years. For data science or heavy computation, look at the other runtimes listed above.
Will the developer work during my business hours?
Part of their day overlaps yours. India keeps one time zone, UTC+05:30, with no daylight saving, so a 9 AM standup in New York lands at 6:30 PM in Delhi while the US is on daylight saving time and at 7:30 PM the rest of the year. Our engineers keep hours that face New York; write the agreed overlap into the statement of work. Outside it, production emergencies are covered from Delhi and Sydney.
Can your developer take over an unfinished Node.js project?
Yes, and the first two weeks change shape when they do. The developer starts by running the service, reading its tests and its deploy path, and writing down what is missing or risky before changing anything large: unpinned packages, a Node.js version past end of life, handlers that swallow errors. You get that note first, then a proposal for what to fix in what order.
