React Native looks deceptively simple from the outside. JavaScript on both platforms. One codebase. Hot reload. The reality, for any app past the prototype stage, is harder: navigation patterns that work on iOS but stutter on Android. List performance that collapses past 500 items. Native module integration when the JS bridge can’t do what you need. Permissions, deep linking, push notifications, and in-app purchases- each one a quirk per platform. Version upgrades that break native dependencies. New Architecture migration that touches every native module you’ve written.
Guru TechnoLabs React Native developers are hired for that work. They’ve shipped production React Native across travel and booking platforms, on-demand services, SaaS products, social and dating apps, marketplaces, and B2C consumer apps environments where the app runs on hundreds of thousands of devices and the next release can’t break the previous one.
You can hire them as a long-term extension of your mobile team, embed them into your existing engineering squad, or scale specific capabilities: feature development, native module work, version upgrades, performance optimization, migration from native to React Native, or brownfield integration of RN screens into an existing native app.
Our React Native developers are placed based on demonstrated production experience - not certifications. Below is the technical depth they bring to your team.
React Native 0.74+ with New Architecture (Fabric renderer + TurboModules) enabled, JavaScript and TypeScript, Hermes JS engine, JSI for native interop, function components with hooks, custom hooks for shared logic, React 18 concurrent features where they earn their complexity.
Expo SDK 50 / 51 / 52, Expo Router for file-based navigation, EAS Build for managed iOS and Android builds, EAS Submit for store submission, EAS Update for over-the-air updates, Expo Dev Client for native dependency development, prebuild and config plugins for native customization within the managed workflow.
TanStack Query (React Query) for server state, Zustand and Jotai for lightweight client state, Redux Toolkit + RTK Query where Redux is already the standard, React Context for narrow shared state, MMKV and AsyncStorage for persistent local storage, WatermelonDB and Realm for offline-first apps.
React Native Reanimated 3 with Worklets, React Native Gesture Handler, React Native Skia for advanced 2D graphics and shaders, React Native Vision Camera, FlashList for high-performance long lists, Tamagui and NativeWind for styling systems, custom design-system implementation.
React Navigation 7, Expo Router, deep linking, universal links, dynamic links, tab/stack/drawer patterns, modal stacks, authentication-aware navigation flows.
TurboModules and Fabric components in Swift and Kotlin, custom view managers, bridging to existing native iOS (Objective-C / Swift) and Android (Java / Kotlin) codebases, integrating React Native screens into existing native apps (brownfield), embedding native modules into managed Expo projects via config plugins.
Jest with React Native Testing Library for unit and component tests, Detox and Maestro for end-to-end mobile automation, snapshot testing where it earns its place, and accessibility testing. Our developers also maintain legacy Enzyme test suites where they still exist, and have shipped Enzyme - React Native Testing Library migrations for teams stuck on deprecated tooling.
Performance profiling with Flipper and the React Native DevTools, Hermes profiling, JS thread and UI thread analysis, Sentry and Firebase Crashlytics for production crash monitoring, Firebase Performance for real-user metrics, memory leak detection, bundle size optimization.

Flight, Car, and Hotel Booking App
LooneyTrips is built with the primary intention of making bookings convenient and easy for people. The client wanted to provide a platform on which people can make flight, car, and hotel bookings effectively. The client shared his business requirements and goals with us.
We scheduled some meetings with the client to decide the main goal and purpose of the idea. Later, we finalized all the features & functionalities and decided to create a travel app.
Local Business Listing App
The client already possesses a local business listing application. He was planning to introduce something new for app users. He contacted us with the requirement.
We analyzed the entire application and suggested some feature enhancements. Our team started working on the project quickly. People running different businesses in a region can register themselves on the app. Users in any region can search for businesses such as salons, gyms, and grocery stores.
Question & Answer App
The core purpose of DreamIL is to provide correct information to people traveling or migrating to a new country in the form of a question-and-answer. The client wanted to offer answers to various questions on multiple platforms. He approached us with the requirement.
We suggested to the client to create an app using a cross-platform framework. Our team analyzed all the things needed for the app and started working. We delivered a user-friendly and scalable mobile app. The app allows admins to post relevant queries and articles.

Get updated with the latest industry trends, analysis, and tech news.
Share your requirements — React Native version, scope, seniority level, timeline. We send shortlisted developer profiles within one business day. You interview directly, choose an engagement model (full-time, part-time, or hourly), and the developer joins your sprint cadence within days.
Rates depend on seniority, engagement model, and scope. Mid-level React Native developers start at $18/hour; senior engineers with native module experience, New Architecture migration experience, or specialized platform expertise are priced higher. Full-time monthly engagements receive better rates than hourly. Pricing is transparent — no procurement back-and-forth.
Yes. Part-time (80 hours/month) is common for teams that need senior input on architecture, native module work, or version upgrades without a full headcount. Hourly is also available for short, well-scoped technical work.
Most developers we place carry 5+ years of React Native production experience, with apps shipped to both the App Store and Google Play. Senior engineers with 8+ years bring native module fluency in Swift and Kotlin and architecture-level experience with the New Architecture. We don't place junior developers on React Native engagements — production mobile work requires engineers who can make independent decisions.
Yes. New Architecture migration (Fabric + TurboModules) is one of the most common engagement types we run in 2026. Our developers handle migration planning, native module conversion, gradual rollout, and the testing required to ship the migration without breaking the production app.
Yes. We handle both full migrations (native → RN) and brownfield integration (embedding React Native screens into an existing native app). Brownfield is often the lower-risk path for established native apps — your team can adopt RN screen-by-screen without a full rewrite.
Yes. Version upgrades — React Native 0.6x / 0.7x → current, Expo SDK upgrades, native dependency upgrades — are one of our most common engagement types. We resolve breaking changes, replace deprecated packages, migrate legacy testing tooling (e.g., Enzyme → React Native Testing Library), and ship the upgrade without breaking production.
Yes — full-time and part-time engagements are dedicated. Your developer attends your standups, follows your sprint cadence, and treats your codebase as their primary work. Hourly engagements are the only exception, and that's specified upfront.
Our developers manage submission and review-cycle management — including App Store Connect setup, code signing, provisioning profiles, store metadata, review feedback resolution, and staged rollout strategy on both platforms.
Depends on scope, integration count, and clarity of requirements. A focused consumer MVP with three or four integrations typically ships in 8 to 14 weeks. A production-grade app with payments, push, analytics, native modules, and offline support takes 4 to 7 months. We scope after technical discovery, not before — early-cycle guesses aren't useful to either side. See our app development timeline guide for context.
We work inside your communication stack — Slack, Microsoft Teams, Jira, Linear, GitHub, Zoom. You don't set up a parallel workflow. A delivery manager handles engagement health; day-to-day technical conversations happen directly with the developer.
Yes — before any developer profile is shared. We also enforce internal access controls so production credentials, customer data, App Store Connect, and Google Play Console access stay restricted to the assigned engineer.
We replace within 7 working days at no additional cost. Onboarding is documented from day one specifically to make handover viable if the match is wrong.
Yes. Long-term maintenance engagements — covering iOS and Android OS update compatibility, React Native version upgrades, security patches, OTA hotfix releases via EAS Update or CodePush, store submission management, and feature development — are one of our most common engagement types.
Share your business needs or project requirements with us & we will get back to you quickly.
