Hire React developers you can test before you commit
Our React developers, currently based in India, join your team. Before trusting anyone's vetting, ours included, set a 75-minute task marked against React's documentation, and price one with US wage data.
Tell us what you are building
A software engineer usually replies within 24 hours, and a shortlist or a plain no typically follows within a few days.
Why a CV cannot tell you who writes good React
The gap between production React and tutorial React lives in the code, where a CV, a keyword screen and an hour's interview never reach.
Sound familiar?
You promised a date, and this hire stands in the way.
- Everyone lists React, so a keyword screen separates nobody
- You cannot read the code, and whoever can is busy
- Senior titles and junior output, found out in week three
How to hire a React developer: a 75-minute live task
To hire a React developer, set a 75-minute live task on a screen built from your own data. It shows more than any vetting claim, ours included. Run it on anyone, without us. Here is the same live-task test, applied to Node.js developers.
- Before: supply the starter, share the key
A React 19.x repository with StrictMode and eslint-plugin-react-hooks on, a mock API with random 100-1500 ms delays and stable ids, and 30-50 records like your data.
- At the start: set the brief
A list-and-detail screen: text filter, sort, an editable note per row, a detail panel, and a count and total matching the screen. Changing the filter refetches.
- 60 minutes: they build
They build the screen in the starter as they normally would, against the mock API and the sample records, with the marking key already in hand.
- 15 minutes: the walkthrough
They walk you through the code they wrote and explain each useEffect and memo. Drop the inline edit to cut the task to 45 minutes.
Our marking key for React hooks, effects and state, citing react.dev
Several rows need no React to check: the lint output, StrictMode behaviour, typed text after a sort.
| What to check | A pass | A fail | What react.dev says |
|---|---|---|---|
| Rules of Hooks | Hooks at the top level only. | A Hook inside a condition or loop. | “Don’t call Hooks inside loops, conditions, nested functions, or try/catch/finally blocks.”Rules of Hooks |
| List keys | Rows keyed by record id; typed text stays put after a sort. | Index keys; typed text jumps rows. | “Index as a key often leads to subtle and confusing bugs.”Rendering Lists |
| Effect use | The only Effect calls the API; totals are computed in render. | An Effect that sets state from state. | “If you can calculate something during render, you don’t need an Effect.”You Might Not Need an Effect |
| Cleanup and race conditions | Fast typing always ends on the latest results. | An older response overwrites a newer one. | “your cleanup function should ensure that the fetch that’s not relevant anymore does not keep affecting your application.”Synchronizing with Effects |
| Dependency arrays | exhaustive-deps reports nothing; no rule disabled. | Missing dependencies or an eslint-disable. | “Every reactive value used by your Effect’s code must be declared in your dependency list.”Removing Effect Dependencies |
| Purity and StrictMode | No mutation in render; same behaviour under StrictMode. | Sorting state in place, or removing StrictMode. | “By calling the component functions twice, Strict Mode helps find components that break these rules.”Keeping Components Pure |
| State structure | Nothing derivable is stored. | Stored totals. | “Avoid redundant state.”Choosing the State Structure |
| Lifting state up | Filter, list and summary share one parent state. | Two copies synced by an Effect. | “move their state to their common parent.”Sharing State Between Components |
| Memoization | Removing every memo changes nothing. | It breaks or loops without one. | “You should only rely on useMemo as a performance optimization.”useMemo |

In State of React 2025, the two hook pain points respondents named most were useEffect and dependency arrays. Both are rows on the key, and so is memoization.

Three things you can check before you contact anyone: who owns the code, when you talk to the people doing the work, and source code you can read. Ours is public, so run the key on us first. For current practice, see server-rendering React on Cloudflare Workers.

In May 2025, the newest BLS release, the median base wage for US software developer employees was $135,980: $160,920 in Los Angeles and $186,640 in San Francisco. BLS has no React occupation. The closest it measures are Software Developers and Web Developers. Take these to your budget meeting.
Cost to hire a React developer: base wage

San Francisco-Oakland-Fremont, CA
$128,090 to $273,400 · median $186,640
US respondents who identified as front-end developers reported a median total pay of $145,000 in the Stack Overflow Developer Survey 2025, self-reported and including bonuses. Both measure US developers, not Atyantik.
US Bureau of Labor Statistics, OEWS, May 2025. SOC 15-1252 Software Developers, base wage, employees only, 10th to 90th percentile. BLS has no React occupation. Market wage data, not an Atyantik price. Source: BLS OEWS, May 2025 (opens in new tab)
BLS publishes no React developer hourly rate. Its nearest medians, May 2025, run from $44.54 for US web developers to $89.73 for San Francisco software developers. They cover employees only, not freelance or contractor rates.

| Item | Median hourly base wage, USD |

| Software developers, Los Angeles | 77.37 |
| Software developers, San Francisco | 89.73 |
Title and city both move the median.
On average, for US private-industry employees in all occupations, wages are about 70% of what an employee costs (BLS ECEC, June 2026). That month, US private employers paid $46.89 per hour worked: $32.82 wages, $14.07 benefits. These figures cover US employees, not Atyantik, and leave out recruiting and ramp-up.

How an engagement is shaped: team, length and hours
We publish no rate. Either way, a senior software engineer reviews every change, the code and IP are yours from Day 1, and the work lives in your repositories. See also a whole team rather than one developer and what a whole custom software build costs, not only one developer's rate.

Ask about price on your work
A software engineer usually replies within 24 hours, and a shortlist or a plain no typically follows within a few days.
From your brief to code in your repository
- You send the brief
What you are building, what it runs on, how many React developers you need and from when.
- A shortlist, typically within a few days
Named React developers, matched to the work in your brief, each one someone you can interview before deciding.
- You interview, if you want to
How you interview is your choice, including the 75-minute task. If no one fits, another shortlist.
- They work in your repository
Our senior software engineer reviews every change, alongside any review of yours. The code is yours from Day 1.
Where our React developers work, and when
Every developer is currently based in India, so compare the UTC window with your own day. For a fuller comparison, see how nearshore, offshore and in-house compare on overlap and cost. A coordinator-hosted sync or an overlap shift can be arranged on request. If your team is in Los Angeles, see working with us from Los Angeles.

Put the same ownership question to anyone else bidding, in the same words.
Code ownership, and what you keep
You want to end it and the work is held hostage.
Who holds the code when an engagement ends is worth having in writing before you sign anything.
What we commit to
From Day 1, every line of code is your IP, in your repositories and cloud accounts. Taking it back is a permissions change on your side.
Nobody left who knows how it runs.
If nobody is left who knows how it runs, the loss is whatever never got written down.
What we commit to
Any documentation we produce is yours, including the operational runbook: the written record of how your system is run, day to day.
Quality drops once nobody is watching.
Quality slipping once nobody is watching is a problem this engagement was built to remove.
What we commit to
A senior software engineer reviews every change, with unit and integration tests and CI gating every merge, all in your repositories.
When we are the wrong team
Where we fit
You want React software engineers inside your team and review process
You want an inherited React codebase read before anyone proposes replacing it
Whoever signs cannot assess React, so the work must stay visible to someone who can
Where we are not
Your stack is Vue, Svelte or plain JavaScript, and none of the work is React.
You need the whole frontend covered, whatever it is built in, not React specifically.
One person must own both ends of the work, the API as well as the interface.
Your React interface is already too slow, which is a repair job, not a hire.
You are not yet sure the product needs React at all, and want that settled first.
For whoever else has to agree
Paste this to whoever signs or vetoes it. Each line below stands on its own, so it still makes sense pasted into a message.
