01 / Vetting
How we vet React developers before you meet them
Most agencies describe vetting as a rigorous multi stage process and then say nothing about the stages. Here are ours, in the order they run. Every engineer completes all six stages before they are put in front of you, and we have turned down work rather than place someone who didn't.
-
01
Four written answers, before any call
Four questions pulled from real client code. Why does this component re render, what breaks if this effect drops a dependency, where should this state live, what's wrong with this list key. Answers come back in writing and get read with the name hidden.
-
02
A three hour paid build task
A small feature on a repo that looks like production: existing patterns, existing test suite, a slightly annoying API. We pay for the time. We read the PR, not the screenshot.
-
03
Code review, in reverse
We hand them a PR of ours with six deliberate problems in it, two of them subtle. Spotting a bad abstraction is harder than writing a good one, and it decides whether your senior people enjoy working with them.
-
04
React specifics, not JavaScript trivia
Render behaviour, effect timing, where state should live, when memoisation pays for itself, what a Suspense boundary does to your loading states. We follow the reasoning in the React documentation on effects and expect candidates to have read it.
-
05
Written English, judged on real artefacts
Remote work is written work. We read their PR descriptions and issue comments from the build task. Fluent conversation matters less than a clear paragraph explaining a tradeoff at 2am your time.
-
06
A reference call with a former lead
We make the call ourselves, ask what they were like when a deadline slipped, and tell you what was said. If nobody will take the call, that's information too.
When people ask to hire dedicated ReactJS developers in India, this is the part worth interrogating. Ask any vendor to show you the actual questions. If the answer is a slide about culture fit, keep looking.
03 / Engagement
Hire Dedicated ReactJS Developers in India, or a Whole Team?
Everyone starts with the pilot. A real ticket from your backlog, scoped to two weeks, at a fixed fee. You keep the code whichever way the decision goes. What it costs to hire React developers India wide runs from $2,400 to $7,700 a month depending on seniority and hours, and one engineer is dedicated to one client at a time. How that compares with a US salary, a contractor or a nearshore team is worked through in what it costs to hire a React developer, and a whole build is priced differently again, as the cost of a React project shows.
Hire React JS Developer in India: Three Ways to Start
We're not the nine dollar an hour option you'll see advertised. At that price you're buying a seat on a bench, shared across three accounts, replaced without telling you. We'd rather be the third quote and the one you keep.
How the first month runs
04 / Seniority
Seniority: Which Level Fits Which Work
Most enquiries arrive in the singular, hire react developer in india, one person for one product. Every react js developer in india we place sits at one of these three levels, and the most expensive mistake is hiring a lead for ticket work, or a mid engineer for an architecture decision.

05 / Failure modes
What Goes Wrong When You Hire React Developers in India
We've watched all six of these end engagements, including two of ours. Read them as things to check on your side, because four of them aren't about the engineer at all.
06 / Paperwork
Contracts, IP assignment and the W-8BEN-E
Nothing here is unusual. It is listed because most vendor sites don't list it, and your legal team will ask anyway.
07 / Tooling
Hire ReactJS Frontend Developers in India for Interface Work
A short list, on purpose. If your stack differs, say so on the call and we'll tell you honestly whether that's a week of ramp or a bad fit.
React 19
Hooks and Suspense boundaries used deliberately, not sprinkled.
TypeScript
Strict mode. No implicit any survives review.
Vite
Where SSR earns nothing. Builds that stay fast at year two.
TanStack Query
Server state here, Zustand or Redux Toolkit only when it is genuinely client state. Rarely both.
Vitest
Units and components, plus Playwright on the three flows that must never break. Testing Library, run on every PR before review starts.
Eight tools, not forty logos. Anything outside this list is a week of ramp we will quote for honestly, or a bad fit we will tell you about on the call.
08 / Next.js
Hire Next JS Developers in India, or Plain React?
Next.js is React with a router and a rendering strategy attached, so the question is not who you hire but what your project needs. Where the reason is search traffic, our React SEO guide shows how to check what Google actually indexed before anyone migrates anything.
When rendering earns its complexity
Search traffic matters and pages must render server side
First paint is a business metric, not a preference
You need file based routing and a team convention around it
Content and marketing pages sit alongside the app
App router. Server components where they help, not everywhere
When it does not
The product sits behind a login and Google never sees it
An internal tool, dashboard or admin console
You want the simplest build and deploy story available
Your team has no appetite for framework upgrade cycles
React 19 with Vite. Fewer moving parts, faster builds
People ask this three ways, hire next js developers in india, hire next.js developers in india and hire next js developer in india, and the honest answer is that it is the same engineer. Same rates either way, and the same six vetting stages. We do not price Next.js as a premium skill, because treating it as one is how studios end up recommending it for admin panels. If you already run Next.js and want someone who can read an app router codebase without a fortnight of ramp, that is what a senior React engineer is.
The migration case
Most Next.js enquiries we get are migrations, not new builds: Create React App to Vite, Vite to Next.js, or pages router to app router. Those are scoped jobs with a measurable before and after, and they are the work we would rather quote. Send the repository and the reason you want to move, and you get a written recommendation including "stay where you are" if that is the answer.
09 / MERN
Hire MERN Stack Developers in India, With One Substitution
If you searched hire mern stack developer in india, we are most of what you want and we will tell you which letter we would change. Three of the four are exactly what our React and Node development studio does all day.
MongoDB
We would argue for Postgres
Express
Or Fastify. Same shape
React
Every frontend we ship
Node
Every backend we ship
The M is the one worth a conversation. MongoDB is a good fit for genuinely document-shaped data that nobody needs to join. Most products we are asked to build are not that: they have users, orders, permissions and invoices, all of which relate to each other, and modelling those as documents means writing joins by hand in application code. We have inherited three of those and each one cost more to unpick than the schema would have cost to design.
Keep MongoDB when
The data really is documents: logs, events, CMS content, flexible payloads
It already runs in production and the schema is settled
Your team knows it and nobody wants to learn Postgres this quarter
Take Postgres when
Entities relate to each other, which is nearly always
You will need reporting, and someone will ask for SQL
Correctness matters more than write throughput
None of that is a reason not to work with us. If you want to hire mern stack developers in india and keep Mongo, we will build on it and say nothing further. If you are still choosing, you get the argument above in writing before any code is committed, which is the same standard as every other decision on this page.
10 / FAQ
Questions we get asked
The questions that decide an engagement, answered before you have to ask. If yours is missing, send it and we will add it here.
11 / Evidence
One engagement, start to finish
A pilot that became eleven weeks of work. Written up with the figures and the credit metering decision we got wrong.
Where to go from here
If you've read this far you're probably comparing three or four vendors. Two things worth doing before you decide: ask each one for the actual vetting questions they use, and ask who owns the repository during the engagement. That holds whether you want a react development team, a react js developer company, or to hire a remote React developer one person at a time. The answers sort the field quickly, and the other checks, from the proposal to the reference call, are in comparing React studios before you sign.
When the backend needs building as well as the interface, the vetting for Node JS developers differs in ways that matter, and if you'd rather not manage an engineer at all, fixed scope delivery builds the thing to a date. Every stage of the vetting on this page, with the actual questions we put to React candidates, is written out in how to hire React developers, and finished work is in the case studies. Read the one where we got the decision wrong; it tells you more than the one where we didn't.
