LinkedIn →Hire React developers
who read the codebase before they touch it.
A dedicated engineer, or a small team, who treats your existing repo as something to understand before it's changed, not a blank canvas. Vetted against real code and real pull requests before they ever see yours, working inside your CI and your stand-ups, and scaling up or down monthly without a hiring cycle. You meet the engineer directly, and on request review their real code under NDA, before a contract is signed.

What you get
Hiring a React developer through PixelCrayons gets you a vetted frontend engineer working inside your repo. They build with TypeScript, hooks and component architecture, integrate with your APIs and treat Core Web Vitals as a shipping requirement, with a named coordinator and escalation contact behind them. You interview the engineer first and scale monthly.
- Vetted on real code, not puzzlesEvery engineer has shipped against live codebases under our review standards before yours.
- Cover when a sprint can't slipA named coordinator, an escalation contact and a named second React engineer who knows your repo.
- Team integration, not a ticket queueYour repo, your stand-ups, your CI and your Slack, following the patterns already there.

What they cover
Component skills,
commercially wired.
Not a coder who happens to know React. An engineer whose job includes the codebase's future: what the next person inherits, and whether the tests still mean anything a year on.
Core engineering
- React hooks and component composition patterns
- State management: Redux Toolkit, Zustand, Context API
- TypeScript across the component tree, not bolted on after
- Component architecture built for reuse across a product, not just one screen
- Testing: Jest, React Testing Library, Playwright
The surrounding stack
- Next.js: App Router, server components, rendering strategy
- REST and GraphQL API integration
- Headless CMS and commerce backends: Contentful, Shopify, custom services
- Core Web Vitals and rendering performance as a build constraint
- Auth, forms and the plumbing that features actually depend on
The commercial layer
- Code review as a discipline, not a formality before merge
- Handover documentation written for the next engineer, not just this one
- Working inside an existing codebase without rewriting it out of habit
- Accessibility: components that conform to WCAG, not just pass a linter
- Estimation and scope conversations without invented precision
In practice
What a React developer
actually does all week.
The shape of the work, the questions that separate candidates, and the setup that stops week one being wasted.
The shape of a working week
Most weeks mix new screens with work on what's already there. A feature arrives as a ticket and a design; the developer builds it as components that match the existing patterns, writes tests with React Testing Library, and opens a pull request small enough to review properly. Alongside that: a re-render traced with the React Profiler, a Context split so one update stops refreshing half the app, a dependency upgrade that needs the tests to prove nothing changed. On a Next.js app, part of the week goes on deciding what renders on the server and what needs the client.
Questions that separate candidates
Ask when they would lift state up, when they would reach for Context, and when a store like Zustand earns its place. Strong answers start with 'it depends' and then say on what. Show them a useEffect that fetches data and ask what's wrong with it; good candidates spot the missing cleanup, the race condition and the case for a data-fetching library. Ask how they would type a component that accepts children and a variable element type. Ask what they would test and what they wouldn't. Confidence about every library is a weaker signal than clear reasons for choosing between them.
Set these up before day one
Repo and CI access, a working local setup with seed or mock data, and credentials for a staging environment. Share the design files and whatever component library or Storybook exists. Write down the conventions that live in people's heads: how state is organised, where API calls belong, which patterns are being phased out. Tell them which React and Next.js versions you're on and whether an upgrade is planned. Name one reviewer for their first pull requests. Developers who arrive without these spend the first week asking, and the answers they get are rarely consistent.
Common ways the hire goes wrong
The most frequent problem is scope: a React developer briefed as the whole frontend team, expected to own design decisions, the backend API and deployment as well. Decide what they own. The second is a codebase with no agreed patterns, where each new developer adds a different state library. Give them the authority to propose one and retire the rest over time. The third is hiring for a problem that sits elsewhere: if pages are slow because the API is slow, no amount of memoisation helps. A good developer will tell you so in the first fortnight.
How it works
Brief to embedded,
interview before signing.
Start
Brief and a call
We sign an NDA and you describe the repo, the stack and the gap.
Once the brief is complete
Proposal and interview
We confirm when your proposal arrives and propose the engineer whose pull-request history fits. You interview them and review a code sample before anything is signed.
Your decision
You sign off
You confirm the scope, the payment and the access we need. Nothing starts before this.
Typically 2 to 3 business days later
The engineer starts
They read the codebase before changing anything, and join your CI pipeline and review process.
Every month
Scale either way
Add a second engineer when the backlog grows; step down when it doesn't. Each month the engagement can resize, adding React capacity without a headcount decision.

Why through us
The engineer,
plus the review discipline.
Hiring an engineer on their own gets you their code. Hiring through a delivery organisation adds the review standard and cover that keeps pull requests landing on schedule.
Vetted on real code, not puzzles
Every engineer on the bench has shipped against live codebases before yours. That work ran under our own review standards, pull requests reviewed weekly, held to the same bar you'll see. A whiteboard exercise shows how someone reasons under pressure; a history of merged pull requests tells us more about how they actually build.
Cover when a sprint can't slip
You get a named coordinator, an escalation contact and a named second React engineer. Briefed on your repo from day one, following the open pull requests as they land. Leave or a departure means they pick up the next ticket without a ramp-up: the things a lone freelancer can't offer and an in-house hire needs a whole team to cover. You get an engineer and the delivery structure behind them.
Team integration, not a ticket queue
Your repo, your stand-ups, your CI, your Slack. Dedicated means embedded in how you already build, reading the existing patterns and following them, not tickets thrown over a wall into someone else's queue.
Quality governance you can audit
A weekly review in Prism, written up and tied to what shipped, pull requests reviewed against a documented standard, and decisions about scope or trade-offs logged rather than made in a hallway. Unsure what you're paying for? The pull request reviews and decision log answer before we do.
Side by side
How you typically hire,
versus through us.
A full-time in-house hire earns its keep once React work is permanent and central to your product roadmap, and we'll tell you plainly when it is. This page covers every other case.
| Hiring it yourself | Through PixelCrayons | |
|---|---|---|
| Time to a productive engineer | A full recruiting cycle: sourcing, technical screens, notice periods, ramp-up on your codebase | Eligible engagements can typically start within two to three business days after scope, payment and required access are confirmed |
| Vetting | Take-home tests and whiteboard exercises: signal that doesn't always predict real delivery | Pull-request history on real codebases under our own review standards, checked weekly |
| Management overhead | Yours entirely: objectives, code-review cadence, career development, leave cover | A named PM and escalation path included; you review pull requests, not manage a headcount |
| Scaling | A new hiring cycle each direction: months up, severance and notice periods down | Resize monthly: add an engineer or step down with a conversation |
| Risk when it doesn't work | A mis-hire costs velocity until it's caught, then a difficult, notice-bound exit | Propose-again is built in; the setup notes and open pull requests transfer with the handover |

Before you sign
Our commitments
Each one says where it applies and links to its full terms.
14-Day Risk-Free Trial
For eligible managed specialists. Up to 14 calendar days or 80 logged working hours, whichever comes first. End within the trial and pay nothing for eligible trial hours. Continue beyond it and those hours are billed at the agreed rate. Unpaid trial work remains ours if you stop.
Eligible managed-specialist roles only, one trial per customer. Not offered for AI, chatbot, prompt, automation, API-integration or QA work. Brand and graphic designers, brand strategists, video editors, content writers, copywriters and content marketers start with a paid pilot.
Full termsTime-zone overlap
At least four hours a day inside your core working hours. Two hours plus a daily written handover for the US West Coast.
Managed specialists only; not a staffing promise for project teams.
Full termsClear IP & Ownership Terms
Your materials remain yours. Bespoke deliverable rights, licences and handover are agreed before work starts.
All engagements.
Full termsClear Delivery & Escalation Ownership
Know who coordinates your engagement, who owns the work and how to escalate an issue.
All engagements. Roles may be combined and vary with your engagement.
Full termsWhy not just hire a freelancer?
A freelancer can be the right choice for a single, well-defined task. We are set up for work that needs an accountable team: a named coordinator, delivery reviewed by QA and a senior lead before release, and continuity arrangements written into the engagement. Confidentiality, ownership and escalation terms are agreed in writing before work starts.
How does time-zone overlap work?
Your engineers work at least four hours a day inside your core working hours. We set the window with you before the engagement starts and hold it for as long as the engagement runs. For the US West Coast the live overlap is two hours each morning, with a written handover at the end of every Indian day. We do not run night shifts: engineers who work nights leave quickly, and keeping the same people on your team matters more to us than a longer overlap.
Can we try you before we commit?
For eligible managed specialists, yes: up to 14 calendar days or 80 logged working hours, whichever comes first. Stop within it and eligible trial hours are free; continue and they're billed at the agreed rate. Unpaid trial work stays ours. Project work and other roles get a paid pilot with scope, acceptance criteria, duration and fee agreed first.
What if we want to stop?
Cancellation, notice and any renewal terms are written into your proposal or statement of work before you accept it. If an engagement ends early, we hand over completed, paid-for work and list any unfinished work separately. For an eligible specialist trial, you can stop within the trial window and pay nothing for eligible trial hours.
How we handle claims, credentials and your data: group credentials, dated ratings, how case figures are signed off, client permissions and data handling.
How we vet
How we vet a React developer
on clear reasons, not every library.
Take-home tests and whiteboard exercises do not always predict real delivery. The vetting looks at pull-request history, then at how the developer reasons about state, effects and tests.
- 01Shortlist on pull-request historyWe propose the engineer whose pull-request history on real codebases fits your repo, stack and gap, held to our own review standards and checked weekly. You can review a real code sample from something they shipped, under NDA.
- 02Interview on where state livesAsk when they would lift state up, reach for Context, or let a store like Zustand earn its place. Strong answers start with 'it depends' and then say on what. Confidence about every library is a weaker signal than clear reasons for choosing between them.
- 03Show them a data-fetching useEffectAsk what is wrong with it. Good candidates spot the missing cleanup, the race condition and the case for a data-fetching library. Then ask what they would test, and what they would not.
- 04The trial: read, then small pull requestsIf you take the trial, it runs on a scope agreed before it starts. Expect the codebase read and written up first, then features built to your existing patterns, tested with React Testing Library, in pull requests small enough to review properly.
Questions
Frequently
asked.
Once we have a complete brief, we confirm when your proposal arrives, and you interview the engineer before anything is signed. Eligible engagements can typically start two to three business days after scope, payment and required access are confirmed. Expect the first week to go on reading your codebase before writing to it.
The NDA comes first, then repo and CI access. The engineer reads the existing codebase and writes up what they found, patterns, gaps, anything that looks like debt, before the first sprint's priorities get agreed. Your stand-ups include them from week one, so learning the codebase happens within your process, not off to one side.
Pull requests reviewed against a documented standard before merge, whether that standard is yours or one we propose and you approve. Weekly, written reporting covers what shipped, what's in review, and what's blocked: sprint velocity beside the actual pull-request list, not a vague progress summary. Agencies placing an engineer against client work get it in their own templates.
One is the normal starting point: a single React developer covers most feature backlogs comfortably. A second pair of hands (a backend engineer, a QA specialist) joins when scope justifies it, and the monthly resize works in both directions. We'd rather start with one React developer than sell a team your backlog doesn't need.
Hiring an engineer on their own gets you their code. Through us you also get a documented review standard, a named coordinator, an escalation contact and a named second engineer briefed on your repo from day one. Leave or a departure means the next ticket gets picked up without a ramp-up.
Say so early and we put forward another React engineer; that option is built in. Whoever replaces them inherits the setup notes, decisions and open pull requests, so the switch costs days, not a restart. The proposal names the second engineer and whether their cover is in the monthly rate.
Interview the person,
not the portfolio.
Brief us on the repo and the gap, and meet the actual engineer before anything is signed. If what you really need turns out to be a project rather than a person, we'll say so on the first call.
