Dedicated Resource · React Native
React Native is worthwhile when someone has already dealt with native modules, performance, and store reviews. Typescriptaz provides dedicated React Native developers—not web developers with an Expo tutorial. A mobile slice in your backlog, from navigation to release.
Use
Your React Native developer builds apps that don't feel like web views: smooth animations with Reanimated, native gestures, and robust offline states. They know Xcode and Gradle quirks and what Apple and Google look for in reviews.
Since Expo SDK 55, React Native runs exclusively on the New Architecture. Older apps therefore need to be migrated—including native modules that still use the old bridge. We plan the migration, test thoroughly, and deliver it with your regular releases. You share logic and types via TypeScript With your web frontend.
For decision-makers, apps are mainly about reliability: stable releases, good store ratings, and a codebase that doesn't break with every OS update. That's what our work is geared toward.
Typical mandates: Companion apps for SaaS, marketplaces, and field-service tools.
Tools: React Native, Expo, TypeScript, EAS, Detox

150 hours, directly employed and dedicated solely to your backlog. At kickoff, you meet the person before work begins.
Quick explanation
React Native is a framework from Meta for building native apps for iOS and Android with React and TypeScript. Unlike hybrid web apps, it uses real native UI components. Expo provides a platform that greatly simplifies builds, updates, and access to device features. Since Expo SDK 55, the framework runs exclusively on the New Architecture. For businesses, this means a single codebase for two platforms and the ability to share logic with the web frontend.
Expertise
Seniority isn’t shown on the resume but in code review. Our team looks for it with React Native.
01
A senior React Native developer knows not only JavaScript but also Xcode, Gradle, permissions, and the lifecycles of iOS and Android. That's critical once native modules, push notifications, or background processes come into play.
02
Smooth lists, UI-thread animations with Reanimated, and careful memory usage make the difference between an app that feels native and one that stutters.
03
Signing, build pipelines with EAS, TestFlight, internal test tracks, and store policies: whoever masters this process delivers updates to the stores predictably and without surprises.
04
Field or mobile apps must work offline. Local data storage, conflict resolution, and clean synchronization are among the most demanding tasks that a senior should master reliably.
05
Push notifications, location services, and background tasks are subject to strict rules from Apple and Google. A senior developer implements them so they work reliably and comply with store policies.
06
With TypeScript and shared packages, you can share validation, data models, and API clients between the app and the web frontend. That saves duplicate work and prevents divergence.
Typical situations
01
With React Native, the app for iOS and Android is built from a single codebase — maintained by someone who already understands your web logic.
02
Old React Native version, outdated native modules, build issues with new Xcode versions? We bring the app up to date.
03
Field service apps must work offline and sync later. We build robust data persistence and conflict resolution.
Risk under control
In mobile apps, risks often come from the outside: new OS versions, store policies, device variety. We actively mitigate these three:
Since Expo SDK 55, only the New Architecture exists, and new iOS and Android versions require current toolchains. We keep the framework, Expo, and native dependencies up to date so updates don’t become a major project.
A rejected update can delay a launch. We know the store policies, check permissions and privacy disclosures in advance, and plan buffer time for review.
What runs on one test device crashes on another model. With crash reporting, tests on multiple devices, and staged rollouts, we catch issues before they affect all users.
Over‑the‑air updates are convenient, but they may only include certain changes and must match the installed app version. We version OTA updates cleanly, test them in advance, and can roll them back quickly if problems occur.
Transparency
Business case
A dedicated React Native developer pays off through a shared codebase for iOS and Android. Instead of two teams, one person works across both platforms, and logic can be shared with the web. Stable releases and good store ratings reduce support load and help acquire new users. And OTA updates deliver small fixes quickly without each change needing a store review.
The first two weeks
Analysis, first delivery, clear plan. Read about how we work in general at How we work.
01
React Native version, architecture, native dependencies, crash reports — we assess the app's technical health.
02
Initial features or fixes go to review and ship in the next test build for TestFlight and Google Play.
03
You receive a plan for upgrades, new architecture, and the release process—aligned with your store schedule.
After kickoff
How a typical engagement develops after the first two weeks—aligned with your backlog.
01
Technical status, crash reports, and initial fixes in the next test build.
02
Migration to the New Architecture, updates to native modules, and an automated build-and-release process.
03
Regular releases with staged rollouts, crash and performance monitoring, and a roadmap for new features.
Example scenario
A service company uses an app for field technicians. In basements and rural areas, the network often fails and entries are lost. A dedicated React Native developer builds local storage with synchronization and conflict resolution.
In parallel, the app is migrated to the New Architecture and rolled out to engineers in a phased introduction. Entries no longer get lost, and the app starts significantly faster.
For the service company, this means less rework in the office, complete service reports, and technicians who can rely on their app.
Collaboration
A migration to the New Architecture or a single feature package is well-suited to an hour bundle. If your app requires regular releases and grows with the product, a person on a monthly plan is the right choice.
The discovery package starts with an app audit—ideal if you want to understand the state of versioning, architecture, and stability.
All rates, pools, and effective prices are detailed in the Pricing table.
Straight talk
Cross-platform development isn’t the best choice for every app. For applications with very specific hardware use, complex 3D graphics, or extremely high performance requirements, purely native development can be a better fit. We evaluate this with you upfront and, if needed, recommend combining React Native with native modules.
For IT decision-makers
Has the person themselves published apps to the App Store and Google Play?
Do they know the New Architecture and have they already migrated to it?
How are native modules and permissions handled?
What experience does she have with offline functionality?
How do you monitor crashes and performance after a release?

Frequently asked questions
For most new apps, we recommend Expo: faster builds, OTA updates, and less native maintenance overhead. With development builds and config plugins, custom native modules are no problem.
Yes, as a brownfield integration. React Native screens can be embedded into existing iOS and Android apps, so you can migrate area by area.
Yes. Signing, store listings, review feedback, and OTA updates are part of the job for us—including deciding what can be delivered via an update and what requires a new store release.
Tablets: yes, with an adapted layout. For the web there's React Native for Web, suitable for simple UIs. For complex web applications, we generally recommend a dedicated frontend with shared logic.
We store sensitive data encrypted in the platform's secure storage; connections run over TLS, and keys don't belong in app code. Development is carried out within our ISMS according to ISO 27001.
In addition, there are developer accounts with Apple and Google, possibly build and update services like EAS, as well as the backend and monitoring. We help you realistically plan these ongoing costs.
Development depends on the scope. For the Apple and Google review, we plan a buffer of several days. With prepared store listings and verified privacy disclosures, the process usually runs smoothly.
In most cases, yes. We adapt modules still using the old architecture to the New Architecture or replace them with maintained alternatives.
With unit tests for logic, component tests, and end-to-end tests with Detox or Maestro on real devices and simulators. Before each release, there are also test builds for your team.
In most cases, the vast majority. Platform-specific code usually remains limited to individual modules, permissions, or design details.
Yes—usually in stages. For native apps, React Native can initially take over individual areas. When switching from Flutter we plan a staged redevelopment, prioritized by value.
Bottom line
A dedicated React Native developer reliably brings your app to iOS and Android—with a single codebase, scheduled releases, and stable performance. You eliminate the need for a second team, respond faster to user feedback, and keep the app on a current, supported version.
