Build your career as a React Developer
Projects where the component is yours: which screen gets built, how state gets decided and who tests the result. Shakers connects you with teams whose product already lives in React and needs exactly your stack.
Going solo with React usually starts on a marketplace where you bid on price or on the Reddit thread explaining how to monetise the library. Neither shows how project work actually runs: defined scope, named company and deliverables you can point at.
What follows is not a study route: it is what gets touched on a real project, what you are asked to prove and where your brief ends.
- Higher-paying projects
- More continuity between projects
- Greater recognition for your experience

Amelia
AI Agent Developer
“I have been building AI agents for years. Thanks to Shakers I stopped chasing clients and started genuinely choosing which projects I wanted to work on. I work with some of the best companies in Europe, at my own rate, and I focus on what I am good at and what I love: building.”

Luz
Backend Developer & Data Engineer
“Shakers adds a lot of value because it connects you with sharper projects, already filtered and better defined. It saves you a big part of the upfront work of understanding the client, quoting and weighing up whether it is worth it, and that means that as a contractor you can go far more directly to the opportunities that genuinely fit you.”

Rubén
Software Developer
“Life as a contractor has a lot going on and it is not always easy. We like to focus on what we are good at, but you also have to manage clients, invoicing and go looking for work. For me, Shakers has been key because it does that prospecting for me, it gives the client confidence from the very first moment, and it lets us be part of a community with real enthusiasm.”

Alejandro
AI Developer
“Shakers was key to getting my company off the ground: it gave me the flexibility to keep contracting while I built my next chapter. Without Shakers, I would have had to raise funding or push the project back.”

Toño
Product Designer
“With Shakers I have landed recurring projects that give me peace of mind and room to grow professionally. It is not just about reaching quality clients: it is feeling that you have a network behind you, one that connects you with real opportunities and helps you move forward as a freelancer.”
Join ShakersWhat you can build as a React Developer at Shakers
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 unit of work is the component and their territory reaches rendering, from the SPA to the server with Next.js, and testing with Jest and React Testing Library. If the brief is data or server logic, the role is backend; if the app is mobile, it is another craft.
You touch the whole interface of a React product: TypeScript components, state that does not break at the third requirement and rendering that decides how long the screen takes. What separates a senior: tests with Jest and React Testing Library before anyone asks, accessibility and the one-to-one with design, from approved screen to shipped component.

What a React Developer delivers at Shakers
The brief arrives with the symptom
The SPA that grew, the form that fails on mobile or the pending migration: a concrete interface problem, not a list of technologies.
Components that hold on their own
Documented components, with types and tests. What you deliver is kept by the client's team when the milestone closes, with no calls at three in the morning.
The ecosystem is the craft
Hooks and TypeScript as the base, Redux or Zustand by state, React Query for the server and Next.js if rendering decides. You join on the client's stack.
Interfaces told, not mockups
Having taken real components to production and knowing how to tell it: what you decided, what you measured and what you changed after the first real user.
What gets rewritten and what does not
Prioritising by impact: which component slows the screen down, which state debt blocks the next requirement and what can wait a sprint.
Where your brief ends
You build the interface and its rendering; you hold neither the server nor the mobile app. If the project needs backend or another craft, you say so at kickoff.
Frequently asked questions
Any other questions? Write to us and we will reply.
Is AI going to replace React Developers?
3,080 job ads in Spain ask for react according to Shakers market analysis (n=31,162, September 2026). AI absorbs the repetitive part; the way out is a talent route that certifies the judgement.
What does a React Developer do each day?
Components other teams reuse, state that gets simplified and tests written before anyone asks for them. The screen that does not break on mobile was your best deliverable.
Which tools get used daily?
Hooks and TypeScript almost daily; Redux or Zustand when state grows, React Query for the server and Jest with React Testing Library to test. Next.js when rendering decides.
How much do you earn as a React Developer by project?
The market and the scope set it: which screens get touched, whether there is a migration and what test coverage is required. At Shakers you agree the budget per project before accepting.
How do you start taking on React projects in Spain?
With demonstrable work and a channel that speaks your language: the marketplace makes you bid on price and the forum brings no named company. Certification opens the door the endless form does not.
How do you join Shakers as a certified React Developer?
You create your profile, pass the certification process and enter the collective: only 4 percent make it. Then you choose which React interface projects you take on.
The daily shape of the craft
The component the team asks for today, the state that gets simplified tomorrow and Friday's suite. Fewer wheels reinvented, more interface the team maintains without fear.
The tools are the craft
3,080 active tech job ads in Spain ask for react, according to Shakers market analysis (n=31,162, September 2026). The pair with TypeScript (2,801 ads from the same universe) is the nuclear-stack signal: almost no ad asks for react alone.
How people get here
Two frequent doors: the generalist frontend developer who decides to specialise and the Node full stack developer who consolidates their client half. The junior door exists, but it opens with demonstrable production: living components, not courses.
What this role is not
No server, no database: that is backend. No mobile app either: another craft. Your product is the interface other people use.
Who you share a React project with
A React interface is not held up by one person alone: whoever serves the API, whoever tests and whoever deploys cross your path.
Frontend Developer
The generalist house of the craft: covers Vue, Angular and the whole visible layer. If your profile is not pure React yet, your matching starts there.
Full Stack Developer
The market posts Node+React and .NET+React hybrids: when the brief brings screen and server, this profile covers both layers of the product.
Backend Developer
Node.js, Java or .NET: holds the API and the data your components consume. The classic boundary of your brief, on every project.
Test Automation Engineer
Your components get tested with Jest and React Testing Library; automating the product's whole suite and watching regression is their craft.
DevOps Engineer
Server rendering and the edge cache decide how long your component takes: whoever runs pipeline and deployment crosses your whole project.
Boundaries between these roles are agreed per project: the job title doesn't set them.
