React Developer: what this role brings to your project
A React Developer builds interfaces out of reusable components: state with hooks or with Redux and Zustand, types with TypeScript and server data with React Query. Their territory reaches rendering, from the SPA to the server with Next.js, and testing with Jest and React Testing Library.
Their border with the generalist frontend is depth: where that role covers any framework, this one specialises the product in the React ecosystem. They do not hold server logic: they consume the backend's APIs.

Why work with Shakers
The advantages of adding this profile with Shakers
React specialists, not generalists
We certify identity, experience and technical skills with tests on real components: hooks, types and rendering.
The pair that rules Spanish job ads
React and TypeScript get asked for together in almost every ad: the specialist joins on your real stack, SPA or Next.js SSR.
State architecture, with judgement
Redux, Zustand or React Query by problem: state gets decided by the real size of the brief, not by fashion or inheritance.
Components tested before delivery
Jest and React Testing Library cover the critical component: what your team inherits arrives with its test, not with luck.
From prototype to server rendering
SSR and ISR with Next.js when the screen needs to load fast and rank: the rendering decision gets made with data.
Capacity without growing headcount
A React Developer by project, no hiring process: certified talent that joins on top of your repository and your design system.
Is React frontend or backend?
Frontend: React runs in the browser and its product is the interface. Spanish job ads post .NET+React or Java+React hybrids, but the core of the role is the layer the user touches.
Who helps find specialised React Developers?
Job boards list without a stack filter, agencies sell teams and the talent route presents specialists certified per project. With 3,080 ads asking for react, what is scarce is the criteria.
Agency or by-project specialist for my React product?
It depends on scope: a product from scratch holds an agency package; a living system asks for a specialist by project. Close the doubt with deliverables: which screen, which stack and which deadline.
React or React Native for my project?
React renders in the browser; React Native takes the same craft to mobile apps. For web, this is your specialist; for the phone app, the brief belongs to another role.
How much does it cost to work with a React Developer?
Scope sets it: which screens get touched, whether there is a state or version migration, and what test coverage is required. At Shakers the budget closes per project before kickoff.
How long does it take for a React Developer to join?
Days, not processes: up to three certified specialists in 72 hours, to choose with one technical conversation. Speed does not replace judgement: it brings it forward.
What gets delivered in the first weeks
An audit of what runs: untouchable components, duplicated state and missing tests. The first critical component lands on your design system, with types and its test.
A market that asks for react by name
3,080 job ads in Spain ask for react (Shakers market analysis, n=31,162, September 2026). Ecosystem included: TypeScript in 2,801, Next.js in 344 and Redux in 216. The brief is the stack, not the library.
Where a React Developer ends
At the interface and its rendering. If the role mixes screen and server (.NET+React, Java+React), the brief is full stack; if the data fails, backend. And the mobile app is another craft.
Agency, marketplace or talent route
The buyer looks for a channel, not a CV. It depends on scope: a product from scratch holds an agency; a living system asks for a certified specialist with a closed scope.

Frontend Developer
The generalist house of the interface: covers Vue, Angular and the whole visible layer. If your product does not live in React yet, the brief is decided there.
Full Stack Developer
The market posts .NET+React or Java+React hybrids: when the brief brings screen and server in the same job, this profile covers both layers.
Backend Developer
Holds the API and the data your components consume: if what fails is what arrives rather than what gets painted, the brief moves to their repository.
Test Automation Engineer
Your components get tested with Jest and React Testing Library; automating the product's whole suite and watching regression is their territory.
