Mobile Developer: what this role brings to your project
A Mobile Developer builds applications for iOS and Android and decides the route: native (Kotlin, Swift) when the app squeezes sensors and performance; or cross-platform (React Native, Flutter) when one common codebase serves both stores. Their deliverable is not code on a branch: it is the app published on the App Store and Google Play.
The boundary: they hold the whole app and solve the stack decision; when the brief stays on a single platform in depth, it passes to the Android or iOS specialist.

Why work with Shakers
The advantages of adding this profile with Shakers
Native or cross-platform, with judgement
Kotlin and Swift if your app squeezes sensors; React Native or Flutter if the budget rules. The route is decided with you.
Certified on both routes
We certify identity, experience and skills: native with Kotlin or Swift and apps in React Native or Flutter in production.
Your app on both stores
The deliverable is publication: signed build, App Store and Google Play review and deployment with Firebase and CI/CD.
With a replacement guarantee
If the fit fails, another certified developer joins on the same scope: your app never stops halfway.
Tested on real devices
Every release goes through testing on physical devices: screens, sensors and OS versions, not just the emulator.
One signature from idea to store
Screens, integration with your API and publication with a single counterpart: one person answers for the app.
Native or cross-platform: which development does your app need?
Native if your app squeezes sensors, camera or performance; cross-platform if it is standard and the budget rules. The market backs it: 653 job ads mention android, 382 react native and 182 flutter.
What does a Mobile Developer deliver in the first weeks?
The route decision with judgement, the first screen on the real API and a build tested on real devices, ready for the store rollout that touches.
What stack does a Mobile Developer in Spain master?
The one real job ads ask for: Kotlin and Swift on the native route, React Native and Flutter on the cross-platform one, with Java, SwiftUI, Jetpack Compose, Firebase and CI/CD as the base.
Which is the best AI to develop apps?
The one a developer directs: AI accelerates screens and code, but does not decide the route nor publish to the stores. Certified talent works supported by agents and answers for the whole app.
How much does it cost to work with a Mobile Developer?
Scope sets it: the chosen route, how many screens get delivered and whether publication and maintenance come in. At Shakers the budget closes per project before kickoff.
What if my app only needs Android or only iOS?
The brief narrows to the specialist: Android Developer for Google Play, iOS Developer for the App Store. The umbrella profile picks the route and the project scales without reopening the search.
What gets delivered in the first weeks
The route resolved, the first screen on the real API and a build tested on devices. An app you can touch, not a mockup you get shown.
A market that asks for the role by name
53 active tech job ads in Spain publish the literal Mobile Developer title, according to Shakers market analysis (n=31,162, September 2026). Supply is titled in native and built on two routes: Kotlin and Swift on one side, React Native and Flutter on the other.
Where a Mobile Developer ends
They do not hold your web nor your backend. If the brief stays on one platform, it passes to the Android or iOS specialist; if the app is the face of a whole product, the brief is shared with the full stack.
A brief decision, not a vacancy
The brief arrives with your question: I want an app, what do I need? Stores, screens and integrations close before kickoff.

Find specialists in Tech, Product, Data to complement your team
Android Developer
The native route of Google Play: when your app only lives on Android and squeezes sensors or performance, the brief narrows to their specialist.
iOS Developer
The native route of the App Store: Swift, SwiftUI and Apple's store review. If your app is iOS only, the specialist takes the whole brief.
Full Stack Developer
When the app is the face of a product born whole and also needs web, API and data: one signature for the complete product.
QA Engineer
The regression net of an app that grows across OS versions and devices has its own owner: release without fear when testing enters the brief.
