No commitment · 3 vetted engineers shortlisted in 72 hrs
From SaaS dashboards to cross-platform mobile apps - our React engineers ship production-grade frontend. Here is what they deliver.
Don't see your exact use case? Post your brief and we will match you with the right React specialist.
We match on your full stack - framework, state management, data fetching, and build tooling. An engineer who knows React but not Next.js App Router costs you weeks.
React Framework · SSR · App Router
The dominant React framework. Server Components, App Router, ISR, and built-in API routes make it the default choice for new React projects requiring SEO or full-stack capability.
Cross-Platform Mobile · iOS + Android
Share code between iOS and Android without sacrificing native performance. Expo simplifies toolchain, bare workflow allows native modules. The dominant cross-platform mobile choice.
Full-Stack React · Nested Routing · Forms
Remix co-locates loaders and actions with routes for simple data fetching. Excellent for apps with complex forms, nested layouts, and progressive enhancement without JavaScript.
SPA · Fast Dev Build · No Framework
Vite replaces Create React App for SPAs and internal tools. Sub-second HMR, small bundle, zero configuration. Best when you need a fast SPA without the SSR overhead of Next.js.
Apollo · Relay · Real-Time Subscriptions
Apollo Client or Relay with React powers complex data graphs. Ideal when your data has deep relationships, real-time requirements (subscriptions), or multiple backend data sources.
Type-Safe React · Component Contracts
TypeScript is now standard in React. Typed props, hooks, context, and API contracts prevent entire categories of runtime bugs. Especially valuable in multi-engineer teams and shared component libraries.
Also covering: Gatsby, Astro + React, Electron, Tauri, React Three Fiber (3D), Storybook, Radix UI, shadcn/ui
Post your brief and we will confirm engineer availability for your exact stack within 24 hours.

An honest comparison to help you understand when React is the right choice - and when it might not be.
React is the most faked skill in frontend. These questions expose the difference between engineers who understand React and those who copy-paste hooks from Stack Overflow.
Explain the difference between useMemo and useCallback - and give me an example where using one incorrectly causes a performance regression.
Why it works
Tests real understanding of React's memoisation model. Many developers cargo-cult these hooks without understanding when they help or hurt. A strong answer: useMemo memoises a value, useCallback memoises a function reference, and both only help when the downstream consumer is also memoised - otherwise you're adding cost for no gain.
How does React's reconciliation algorithm decide what to re-render? How does the key prop affect it?
Why it works
Reveals depth of React internals knowledge. Look for: the diffing algorithm, same-position same-type optimisation, and why using array index as key causes bugs in lists that reorder or filter items.
Walk me through your approach to global state management. When would you use React Context versus Zustand versus Redux Toolkit?
Why it works
State management decisions are where mid-level and senior engineers diverge. Expect: Context for low-frequency global values (theme, auth), Zustand for lightweight shared state with selectors, Redux Toolkit for complex event-sourced state with DevTools requirements.
How would you implement server-side rendering in Next.js for a page that shows user-specific data?
Why it works
Tests Next.js architectural knowledge. Look for: getServerSideProps (Pages Router) or async Server Components (App Router), cookie/session handling on the server, and understanding of when SSR is appropriate versus client-side fetching with React Query.
Describe how you would optimise a React component list that renders 10,000 items.
Why it works
Performance at scale is a common real-world challenge. Expect: windowing with react-window or react-virtual, pagination versus infinite scroll tradeoffs, key prop optimisation, and avoiding unnecessary re-renders with memo and stable references.
How do you handle error boundaries in React? Where do you place them and what happens when an error is caught?
Why it works
Error boundaries are a surprisingly underused React feature. Strong candidates know: class component requirement (or react-error-boundary), placement strategy (per route vs per widget), fallback UI design, and logging to error tracking services.
Cannot explain why useEffect fires twice in development
React 18 Strict Mode deliberately double-invokes effects in development to expose side effects. Engineers who don't know this have not read the React 18 release notes and will write buggy cleanup code.
Uses useEffect to derive state from props
Deriving state from props inside useEffect is an antipattern that causes stale state bugs. Strong candidates calculate derived state during render or use useMemo - not effects.
Puts everything in a single context provider
A red flag for mid-level candidates. Global Context for frequently changing values forces all consumers to re-render. Strong candidates split contexts by update frequency or use Zustand/Jotai for fine-grained subscriptions.
Claims 'I always add useMemo/useCallback everywhere for performance'
Premature memoisation is a React antipattern. Both hooks add overhead. They only help when the memoised value is expensive to compute or passed to a memoised child. Adding them blindly makes code slower and harder to read.
No opinion on when not to use React
A sign of shallow experience. Strong React engineers know React adds complexity for simple pages, that static sites may not need it, and that server-rendered HTML is still the right answer for many use cases.

Everything founders and hiring managers ask us before their first React engagement.
Every engineer passes a live coding screen - not a take-home test or an automated quiz. The screen covers: custom hook design, performance patterns (memo, useMemo, useCallback), state management architecture, and a component design challenge. We specifically test for React antipatterns like incorrect useEffect usage, context overuse, and memoisation misapplication. Engineers who passed a bootcamp and know the syntax but not the patterns do not get through. The live React screen covers hooks lifecycle edge cases (stale closures in useEffect, dependency array correctness), useCallback and useMemo misuse patterns that cause silent re-renders, component composition versus prop drilling trade-offs, React Query or SWR caching strategies including stale-while-revalidate behaviour, and accessibility in JSX (ARIA roles, focus management, keyboard navigation). Engineers who rely on component boilerplate without understanding the reconciler do not pass.
You receive 3 shortlisted, pre-vetted React engineers within 72 business hours of submitting your brief. Our AI scans 320+ engineers and a senior React engineer validates each match manually for ecosystem fit (Next.js, React Native, Remix, etc.), seniority, and timezone.
Developer rates range from $20 to $160 per hour depending on seniority and region. Open IT Freelancers adds a flat 15% management fee on top of the developer rate. There is no matching fee - you pay $0 to receive your shortlist.
We match on your full ecosystem. We have engineers specialising in Next.js App Router (Server Components, ISR, streaming SSR), React Native + Expo (cross-platform mobile, offline-first, native modules), Remix (loaders, actions, nested routing), React + GraphQL (Apollo, Relay), and React + TypeScript architecture. Tell us your stack in the brief and we match accordingly.
A React developer specialises in the frontend: component architecture, state management, performance, animations, and browser-side data fetching. A full-stack developer owns both frontend and backend - database design, API development, and deployment alongside the React layer. If your main need is a high-quality UI and you have a backend team or API already, a React specialist is the right hire. If you need one engineer to own front-to-back, hire full-stack.
Yes. Engagements can be as short as 4 weeks (for a sprint or audit) or as long as 24+ months. The only commitment is a 14-day notice period to end an engagement, with no early termination penalties.
If within the first 14 days the engineer is not the right fit, we replace them at no extra cost. No arguments, no delays - we activate the replacement process within 24 hours. After 14 days, engagements run on 14-day notice.
You own 100% of all code, components, design tokens, and documentation. Ownership transfers automatically on work approval through our tri-party contract signed on day one. There are no platform licensing fees or IP held by the engineer or Open IT Freelancers.
We screen for codebase navigation capability, not just greenfield skills. In the brief, tell us your existing stack - CRA, Next.js Pages Router, Redux, etc. - and we match engineers who have worked with similar legacy setups and can ramp up without a full re-write.
Yes. We have a pool of React engineers who also know Node.js, TypeScript APIs, or Next.js API routes - effectively full-stack React engineers. If you need both layers covered by one person, note this in the brief and we will shortlist accordingly.
Toptal's vetting process takes 1-2 weeks and their margin on developer rates is typically 40-60%. We return a shortlist in 72 hours with a flat 15% fee. Our live React coding screen is specific to hooks, performance patterns, and ecosystem knowledge - not generic algorithm tests. We also include managed delivery (weekly reports, milestone tracking) as standard, which Toptal charges extra for.
Timezone is part of our matching criteria. When you post your brief, specify your team's working hours and we will only shortlist engineers with sufficient timezone overlap - typically 4+ hours of shared working time. We have engineers across Eastern Europe, South Asia, Latin America, South-East Asia, and Western Europe.
