Hire React Native Developers

Hiring React Native developers through CodigoDelSur means adding senior mobile engineers, employed by us, who ship one codebase to both the App Store and Google Play from inside your team. They work in your repository and your sprints, and they know what comes after the merge: store review, native modules, device testing and a release that has to go out on two platforms at once. CodigoDelSur has been building software from Montevideo, Uruguay since 2007, for companies in the United States and the rest of the world.

It is the right move when one codebase for iOS and Android fits the product and you want both apps to move at the same pace. It is the wrong move when the heart of the app is real-time camera work or deep hardware integration, where native engineers usually cost less over the life of the product. We tell you which one you are on the first call.

Is hiring a React Native developer the right move for you?

It is when one codebase for both stores fits the product and someone on your side owns the release.

Yes, if:

Your app is already built in React Native or Expo, or you have decided to bring two native apps toward one codebase.
iOS and Android need the same features on the same release cadence.
You have a product owner and someone who reviews pull requests.
Your web team works in React and you want the mobile code to be readable by them.

No, if:

Most of the product is device hardware, background processing or camera frames in real time. That is native work, and our iOS and Android engineers are a different hire.
You only need one platform for the foreseeable future.
You want an app taken from idea to both stores with one company accountable for it. That is full-cycle product development.

How it works, from first call to first release

Five steps, and a mobile hire has one more thing to get right than a web hire: the release. We ask about your stores, your builds and your native dependencies before anything else, and every step ends with a person in your repository or a clear reason not to continue.

Intro call, 30 to 45 minutes. Bare React Native or Expo, how builds and releases are handled today, which native modules the app depends on, and who approves a release. If what you need is native iOS or Android work, this is where we say so.

Written role brief. One page: the parts of the app the engineer will own, seniority, whether store releases are part of the role, overlap and start date. Nothing moves until you sign it off.

Named profiles. Bench first, and we tell you whether the person is on it today or has to be recruited. Each CV names the apps the person worked on and which platforms they shipped to, not an anonymized list of skills.

You run the technical interview. Your process and your bar. A useful exercise for this role is a real bug from your app, because that is where React Native experience shows. You can turn down anyone we propose without giving a reason.

First day and first build. One standard services agreement, signed once. We handle equipment, accounts, background checks where required and payroll. The engineer joins your standup on day one, gets the app building for both platforms in the first days, and aims for a first merged pull request that same week.

How long it takes to add a React Native developer

Five business days from signed agreement to first day as standard, and as soon as the next business day when the engineer is already on our bench.

Stage	Typical time
Intro call to written role brief	1 business day
Role brief to first profiles, if the profile is on our bench	1 business day
Role brief to first profiles, if we have to recruit	5 business days
Interviews	Your calendar, usually within a week
Signed agreement to the engineer's first day	5 business days as standard, or as soon as the next business day if the engineer is on our bench and you are ready
First day to first merged pull request	3 to 5 business days

One delay is specific to mobile: access. Store developer accounts, signing certificates and the build pipeline are the usual reason a first week slips, so we ask for them in the role brief instead of discovering them on day one.

What our React Native developers work on

Apps in both stores: built from nothing, taken over from another supplier, and maintained for years by the same team.

Work	What it involves	Where it shipped
Long running product development	A consumer app developed for close to six years by a dedicated React Native team, on the app and on the Node.js backend	Taste
A product built from scratch	A mobile app for workers and a portal for attorneys, over a calculation engine built with the client	WageWatch
Takeover of an unfinished app	Fixing inherited bugs, stability and performance first, then finishing the MVP and releasing it to both stores	HeyConnect
MVP with Expo	User research, design and prototyping, then a React Native and Expo app released in phases, starting with a beta	StreamWolf

The app side is React Native and Expo, with Node.js on the backend in most of these projects. When a feature needs native code, the same company has iOS engineers in Swift and Android engineers in Kotlin, so a native module does not turn into a blocker. Seniority runs from mid level to tech lead, and we do not place junior engineers in these roles.

What it costs to hire a React Native developer

What a React Native developer costs depends on seniority and on whether store releases and native modules are part of the role, and you get the number in writing with the role brief, before you commit to anything.

The minimum project size is $10,000, roughly one engineer for one month, and the shortest engagement we sign is two weeks, one sprint. There is no recruiting fee, no placement fee and no management fee, and the project manager on our side is included at no additional cost. Billing is per sprint, Net 14, or monthly if your finance team prefers, with volume discounts of 5 percent from five people and 10 percent from seven.

If your app is stuck on a release or a version upgrade, one engineer for one sprint is a real way to find out how deep the problem goes before you plan anything longer.

The React Native projects behind this page

Four clients with a published case study: one kept for close to six years, one built from nothing, one rescued from another supplier and one taken from research to beta.

Taste is a film recommendation app that matches people by taste instead of ranking films by popularity. We took over its existing iOS and Android MVP, stabilised it, and then worked on the product for close to six years, from 2018 to 2024, with a dedicated React Native team on the app and Node.js on the backend. Recommendation apps live with one tension: ask for too many ratings up front and people leave, ask for too few and the matches are poor. That only gets solved by iterating, and one codebase for both platforms is what made six years of iteration affordable, because every change shipped to both stores at once.

WageWatch helps workers check whether they are being paid correctly under US labor law. We built the whole solution: the React Native app workers use to record their contracts and hours, the Node.js backend, the portal attorneys use to organise and assess claims, and the calculation engine, validated through extensive testing and data simulations.

HeyConnect helps groups organise real-life experiences. It reached us unfinished, with a codebase full of bugs and stability and performance problems. A team of frontend and backend developers, a designer and a QA engineer fixed the root causes before building anything new, and the MVP went live on the App Store and Google Play after five months, with an Apdex score of 0.95.

StreamWolf lets people track, cancel and resubscribe to their streaming services from one app. The work went from user research through design and prototyping to a React Native and Expo app over Node.js and Cloudflare Workers, released first to a small beta group whose feedback shaped the next iterations.

React Native developers through staff augmentation, a dedicated team or full-cycle product development

Three different products get sold under the same word, "outsourcing". They are not interchangeable and picking the wrong one is the most expensive mistake in this category. An app in two stores is where the choice between the first two columns matters most, because a release needs more than one person.

	Staff augmentation	Dedicated team	Full-cycle product development
Who owns the roadmap	You	You	Shared, we run discovery
Who manages day to day	Your engineering manager	You, with a CodigoDelSur project manager coordinating on our side at no extra cost	Our project manager
What you get	Individual engineers inside your team	A team shaped around your product, staffed and coordinated by us	A product, from discovery to store release
You need to have	Technical leadership with spare capacity	A product owner and a clear roadmap	A budget and a problem worth solving
React Native work it fits best	Features, upgrades and releases in an app you already ship	An app in both stores owned end to end, with design and QA on the same cadence	A new app, from discovery to both stores
Typical size	1 to 4 people	4 to 12 people	Scoped per project
Minimum commitment	Two weeks, one sprint	Two weeks, one sprint	Quoted per project
Best when	The work is defined and you are short on hands	You own a product area and want it staffed and coordinated as one team	You need the thing to exist and you do not have an engineering org

When this page is not your answer

Do not hire React Native developers to rescue an app whose real problem is the backend, and do not use React Native to avoid a decision about native. If the slow part is the API, a mobile engineer only makes a fast screen wait for a slow response. If the core of the app is real-time camera processing, Bluetooth hardware or heavy background work, a cross platform layer puts one more step between you and the device, and native iOS and Android engineers are the better hire. We would rather say that before you sign than in month four. And if you need design, QA and releases moving together, look at a dedicated team before you add individual engineers.

Where "taking over an app" and "short-term work" fit

Neither is a fourth model. HeyConnect is what a takeover looks like: we review the inherited code, fix what makes it unstable, and only then build on it, either with engineers embedded in your team through staff augmentation or with a dedicated team taking the app over. If the work is short, the two week minimum means one engineer for one sprint, for a React Native version upgrade or a release that is stuck, is a complete engagement.

Frequently asked questions

Do your React Native developers work with Expo?

Yes. StreamWolf was built with React Native and Expo, and Expo is part of the cross platform stack we staff. We also work in bare React Native projects, and when an app needs something a managed setup does not allow, we tell you what moving off it involves before anyone starts.

What happens when a feature needs native iOS or Android code?

Our React Native engineers write the native piece when it is small, and when it is not, it goes to an iOS engineer in Swift or an Android engineer in Kotlin from the same company. You do not need a second supplier to get past a native blocker, and the module ends up in your repository like everything else.

Is React Native the right choice if we also have a React web app?

Often, because your web engineers can read the mobile code and some logic can be shared, but it is not a reason on its own. The platform still has its own work: store releases, native modules and testing on real devices. If your team is hiring for both, a React developer for the web app and a React Native developer for mobile is usually the cleaner split than one person covering two active products.

What time zone do your engineers work in, and how much overlap will I get?

Our engineers work 10:00 to 19:00 Uruguay time, which is UTC minus 3. That covers the entire US East Coast working day, five to six hours of live overlap with the West Coast, and an afternoon overlap with Europe. The schedule is set that way deliberately: shifting the day an hour later widens the Pacific overlap without asking anyone to work nights, and it is the reason this arrangement is still working in month twelve rather than quietly falling apart in month three.

How fast can you actually start?

Five business days from signed agreement to first day is the standard, and if the engineer is already on our bench and your side is ready to receive them, they can start as soon as the next business day. What varies is finding the right person, not starting them: if the profile is on our bench you get CVs one business day after you sign off the role brief, and if the role has to be recruited, first CVs take about five business days. We tell you which of the two you are in on the first call, before you have signed anything, because that is what actually moves your start date.

What happens if the engineer is not working out?

You tell your account manager and we replace the person at our cost. There is no charge for the search and no penalty for asking. The outgoing and incoming engineers overlap for ten business days so that context, access and work in progress transfer inside the engagement instead of landing back on your team, and those ten days are not billed: during the handover you keep paying exactly what you were paying for one engineer. We would rather absorb that than have you carry a bad fit for a quarter, and a company that will not put a replacement policy in writing is telling you something.

Who owns the code and the intellectual property?

You do, exclusively. Everything created for you as part of the work is assigned to you with full title guarantee: source code, application logic, APIs, integrations, data models, configurations, UI and UX designs, documentation and any derivative works. The assignment covers the deliverables as they are created, it is not conditional on final payment, and it is not a licence back to you, it is ownership. We also warrant that what we deliver does not infringe any third party's intellectual property, and where third party material is involved we secure the consents for both sides first. For our own pre existing components that were not written specifically for you, you get a non exclusive, irrevocable, royalty free licence to use, copy and modify them, so nothing we bring with us can be used to lock you in later. Every CodigoDelSur employee signs a non disclosure agreement and an intellectual property assignment as a condition of employment. In practice we also work inside your repositories and your cloud accounts, so in most engagements the code never lives anywhere else to begin with.

Will the engineer work only for us?

A full time engineer works for one client only. If you take someone full time they are on your product and nothing else: your standups, your sprint planning, your Slack, and for practical purposes they are part of your team, with the difference that their employment, payroll and career are our responsibility. If you only need part of a person we do offer part time engineers, and a part time engineer is assigned to a maximum of two projects, never more. We tell you which of the two you are getting before you sign, because "dedicated" is a word this industry uses loosely.

Tell us about your app

Tell us whether the app runs on bare React Native or Expo, what the next release needs and who approves it, and we will tell you on the same call whether the engineer is on our bench or has to be recruited, and what that means for your start date.
