Hire React Native Developer
Cross-Platform Mobile with React Native
Single-codebase iOS + Android apps using React Native and Expo. Typed APIs shared with the web app, native modules in Swift/Kotlin, and OTA updates via EAS.
What We Build with React Native
Cross-Platform Apps
Single-codebase iOS + Android apps with Expo or bare React Native and the new architecture.
Shared Business Logic
Typed API layers and state machines shared with the web app for consistent product behavior.
Native Modules
Custom native modules in Swift/Kotlin for platform-specific integrations that RN libraries don't cover.
OTA Updates
EAS Update and CodePush pipelines for same-day bug fixes without App Store review cycles.
Design Systems
Reusable component libraries with theming, accessibility, and responsive layouts.
Testing & CI
Jest, Detox end-to-end tests, and EAS Build pipelines running on every PR.
React Native Development Services
React Native has become the dominant choice for teams that need a single codebase to serve iOS and Android without sacrificing the feel of a native app. When done right — with proper bridging, platform-specific modules, and careful state management — users can't tell it from a native build. When done poorly, you get janky animations, unpredictable crashes, and a maintenance nightmare that costs more than two separate apps ever would.
ABM Tech has been building production React Native applications since 2016. Our engineers have shipped apps in fintech, healthcare, e-commerce, and logistics — verticals where performance, offline handling, and deep device integrations (biometrics, push, BLE, camera) are non-negotiable. We don't template projects; we architect them around your specific user journeys and release cadence.
Every React Native engagement at ABM Tech pairs a dedicated architect with a tight squad of senior engineers working aligned to your team hours. We handle the full lifecycle — architecture, native module development, CI/CD pipelines, app store submission, and post-launch optimization — so your internal team isn't pulled into mobile firefighting.
The challenge
Most React Native projects fail at scale — not at launch. Performance degrades as the JS thread gets overloaded, third-party libraries conflict on version updates, and native module maintenance blocks every iOS or Android OS upgrade. Teams end up with a hybrid codebase that moves slower than going native would have.
Our approach
ABM Tech architects React Native apps with the JS bundle size, re-render surface area, and native module boundary defined before a line of code is written. We lean on Reanimated 3 and Skia for GPU-bound animations, implement Hermes across both platforms, and write native modules in Swift and Kotlin when React Native's bridge would be the bottleneck. Code sharing targets 85–90% while every platform-specific edge case gets the treatment it deserves.
The outcome
Clients leave with an app submission package built to meet Apple and Google review guidelines — metadata, privacy manifests, entitlements, and store assets prepared before submission so review cycles aren't spent fixing avoidable rejections. Automated E2E test coverage runs via Detox, and a CI/CD pipeline ships over-the-air updates via EAS Update without app-store delays. Typical time-to-first-reviewable-build is four to six weeks for a greenfield MVP, with iOS and Android parity maintained throughout.

Pick the engagement that fits
Four ways to work with us — from surgical staff augmentation to fully managed delivery. All models share the same senior-first talent bench.
Dedicated Teams
Full-time engineers embedded in your team for long-running engagements.
Explore Dedicated Teams↗Staff Augmentation
Add senior specialists to an existing team — vetted, onboarded, and up to speed in weeks.
Explore Staff Augmentation↗Project Delivery
Managed fixed-scope projects with a committed timeline and deliverables.
Explore Project Delivery↗Why ABM Tech
What keeps clients past the first delivery.
What clients tell us made the difference, usually somewhere around the second sprint.
True Native Feel
We use React Native's New Architecture (JSI + Fabric) and platform-specific UI overrides to ensure your app looks and responds like a first-party app on both iOS and Android, not a web wrapper.
Hermes + Reanimated Performance
Every build ships with Hermes pre-compilation and Reanimated 3 worklets so animations run on the UI thread — 60fps scrolling and transitions even on mid-range Android devices.
Single Codebase, 85–90% Sharing
Business logic, navigation, and data layers are shared across platforms. Only device-specific integrations — biometrics, push notification channels, camera APIs — get platform branches.
OTA Updates via EAS
Critical bug fixes and content updates ship to users in minutes via Expo Application Services Update, bypassing the app store review queue without violating store policies.
Security-First Mobile Architecture
Sensitive data stays in the platform keychain, biometric auth flows use native APIs, and certificate pinning is implemented at the network layer — not bolted on after launch.
Observability from Day One
We instrument crash reporting (Sentry), performance tracing, and analytics events during development — not as an afterthought — so you have production-grade visibility at launch.
Why Teams Choose Us
Security built in, not bolted on
Encryption, access control and compliance designed into the architecture from the first sprint — the way our Swedish healthcare consent platform was built.
Working hours that overlap
Singapore-based engineers who keep to your business day, so standups, reviews and decisions happen live rather than overnight.
Top Rated
Near-perfect satisfaction scores across Clutch, DesignRush, and Manifest.
How we work
Scoping call to production release.
Every engagement is staffed with named people whose only assignment is your build. No shared allocation, no roster of contractors matched to a brief.
Week zero
We start by arguing with the brief.
A working session on the problem, not a requirements hand-off.
The first conversation is technical. We go through the system you have, the constraints you are stuck with, and what would count as this having worked — and we push back where the brief and the goal disagree. The people in the room are the ones who would build it, because nobody else can tell you the architecture will not hold.
A walk through your existing stack, data and integration constraints
Run by the engineers who would staff the build, not an account manager
You leave with a scope, a team shape and the risks named out loud
FAQ
The questions that come up before you start.
Engagement models, pricing, security, and how we staff a project — answered straight, with the detail you would ask for on a first call anyway.
A production-ready MVP with core screens, authentication, API integration, and app store submission typically runs $40,000–$90,000 depending on complexity and third-party integrations. Apps with real-time features, offline sync, or hardware integrations (BLE, NFC, camera) sit at the higher end. We provide a detailed fixed-scope estimate after a two-hour discovery session — no vague ranges.
