Projects where the shared app is yours: which component gets reused, which native bridge gets tuned and who publishes on both stores. Shakers connects you with teams whose product needs iOS and Android with the JavaScript stack you already master.
Going independent with React Native in Spanish has nowhere to land: the visible route is global English marketplaces and a forum asking for professionals. This row is that route: projects in Spanish, with scope and an identifiable company.
What follows is not a study route: it is what gets sustained on a real brief, what you are asked to prove and where your territory ends.

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.”

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.”

“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 ShakersA React Native Developer builds apps for iOS and Android with JavaScript and React: reusable components, navigation with React Navigation, state with Redux and bridges to native code in Kotlin or Swift when the product demands it. Their modern tool is Expo, with which they package, update and publish on both stores. The boundary: the web with React belongs to the frontend, the app written per platform to the Android or iOS native, and the server behind it, to the backend.
You touch the app of teams that already live in JavaScript: product apps with an API behind, MVPs that validate fast and views that live beside native modules. What separates a senior: taming navigation and state, tuning the bridge to Kotlin or Swift and publishing on both stores without breaking anything.

The app that ages, the MVP to validate or the native module holding back the release: a concrete app problem, not a list of technologies.
Reusable components, tamed navigation and releases on two stores. What you deliver, the client's team maintains when the milestone closes, without scares.
JavaScript and TypeScript at the base, Expo to package and publish, Redux for state and reading of Kotlin and Swift for the bridges the product demands.
Having published with React Native and knowing how to tell it: which component you decided on, which bridge you wrote and what you changed after the first user.
Choosing between the shared module and a bridge to Kotlin or Swift by real cost, not fashion. Sometimes the one-off native wins, and defending that.
You build the shared app; you do not serve the product's web nor write each platform whole. If it asks for pure native or web, you say so at kickoff.

The component asked for today, the native bridge tuned tomorrow and Friday's release on both stores. Less fighting two codebases and more app the team maintains without fear.
382 active job ads in Spain mention React Native, double Flutter, according to Shakers market analysis (n=31,162, September 2026). It is the cross-platform route with the highest measured demand.
Two doors: the React developer of the web who jumps to mobile with the stack they already know, and the native developer who unifies two apps into one. The JavaScript base shortens the ramp like no other path into mobile.
You do not build the product's web nor write each platform whole. Your product is the shared app. If the brief asks for web or pure native, you say so at kickoff.
A shared app is not sustained alone: whoever decides the route, whoever picks the rival framework and whoever holds the native cross you.
The generalist home of mobile: it frames the native or cross-platform decision. If your mobile profile is not pure React Native, your matching starts there.
The other cross-platform: Dart and widgets against JavaScript and React. They share the decision of one base for two stores; the ecosystem decides the side.
The Kotlin territory of your native bridge: when the module goes down to platform, their repository. Job ads already mix both worlds in the same post.
The other shore of the bridge: Swift and Apple's platform. As with Android, knowing how to read their code widens what your shared app reaches.
Your natural way in: the React of the web shares components and philosophy with you. The boundary is the environment: the web is theirs, the app yours.
Boundaries between these roles are agreed per project: the job title doesn't set them.
