React Native developers build cross-platform mobile apps from a single codebase, helping businesses launch on both iOS and Android without maintaining separate development teams. From startups shipping their first MVP to enterprises scaling internal tools, a skilled React Native developer can accelerate delivery timelines and reduce long-term maintenance costs.
What does a React Native developer do?
React Native developers build cross-platform mobile applications for iOS and Android using a single JavaScript or TypeScript codebase. They create native-feeling interfaces, connect apps to back-end services, and optimize performance across devices, making them a practical choice for businesses that want to reach mobile users on both platforms without doubling development effort.
Common responsibilities for React Native developers include:
Building cross-platform mobile apps with one codebase for iOS and Android
Optimizing app performance through debugging, testing, and load time improvements
Integrating APIs, payment systems, and cloud services like Firebase and AWS
Implementing UI/UX designs using reusable native components
Preparing apps for deployment on the App Store and Google Play
How to hire a React Native developer on Upwork
Whether you need a full app built from scratch, performance optimization for an existing codebase, or ongoing mobile development support, the process starts with a clear job post and ends with a secure working agreement. These steps walk you through finding and hiring the right developer.
Step 1: Post a job
A strong job post helps React Native developers quickly determine whether their skills, experience, and availability match your project requirements.
Specify your target platforms, such as iOS, Android, or both, along with any device-specific requirements
Note whether you're building a new application, extending an existing codebase, migrating from another framework, or maintaining a live app
Include design assets, wireframes, prototypes, or UI requirements if available
Describe required integrations such as APIs, payment processors, authentication systems, analytics tools, push notifications, or cloud services
List technologies and libraries relevant to the project, such as TypeScript, Redux, Firebase, GraphQL, Expo, React Navigation, or native modules
Share expected user volume, performance requirements, offline functionality, and app store deployment needs if applicable
Include your budget, timeline, and preferred collaboration style, whether that's async updates, daily standups, or milestone-based check-ins
Draw ideas from this React developer job description as a starting point
Use our Job Post Generator, powered by Umaโข, Upwork's Mindful AI, to speed things up. Describe what you need in a few sentences, and Uma will draft a job post tailored for React Native developers that you can review and customize.
Step 2: Evaluate candidates
Once proposals start coming in, focus on identifying developers with experience building and maintaining React Native applications similar to yours.
Use Uma to conduct instant interviews, generate candidate shortlists, and compare applicants side by side based on your project requirements
Review portfolios for published mobile apps, cross-platform projects, and applications with functionality similar to your project
Look for experience building and maintaining apps for both iOS and Android environments
Evaluate experience with your required technologies, including TypeScript, Redux, Firebase, GraphQL, Expo, push notifications, authentication, and third-party integrations
Review examples of app performance optimization, app store deployment, and ongoing maintenance work
Check Job Success Scores (JSS), client feedback, and talent badges such as Top Rated, Top Rated Plus, or Expert-Vetted
Review client feedback to look for evidence of strong communication, reliable delivery, and successful long-term project support
Step 3: Interview top choices
Interview shortlisted candidates to evaluate their technical expertise, development process, and ability to support your application's requirements.
Schedule and conduct interviews through Upwork Messages and review transcripts and summaries afterward to compare candidates efficiently
Ask about their approach to application architecture, state management, performance optimization, and cross-platform development
Discuss experience handling app store submissions, app store rejections, updates, and release management
Explore how they approach debugging, testing, crash monitoring, and maintaining application stability across devices
Review experience integrating APIs, payment systems, authentication services, analytics platforms, and cloud infrastructure
Ask how they handle native device features such as camera access, geolocation, push notifications, background processing, and offline functionality
Consider a small paid assessment, such as implementing a feature or reviewing an existing codebase, to evaluate practical problem-solving skills
Use React developer interview questions as a starting point and tailor follow-up questions to your project's technical requirements
Step 4: Agree on scope and begin work
When you've selected a React Native developer, align on technical requirements, deliverables, and project milestones before development begins.
Finalize the project scope, deliverables, timeline, budget, and communication expectations in a formal hourly or fixed-price contract
Define milestones around major deliverables such as application architecture, core features, testing phases, beta releases, app store submissions, and production deployment
Confirm responsibilities for development, testing, bug fixing, deployment, maintenance, and post-launch support
Align on coding standards, documentation requirements, source code ownership, and repository access before work begins
Share design assets, API documentation, technical specifications, credentials, and project requirements through the contract workroom
Use messaging and the contract workroom to manage communication, files, feedback, and progress updates in one place
Take advantage of identity verification, Hourly Payment Protection, and milestone funding tools to support a secure engagement
Track progress against milestones and review deliverables throughout development to ensure the application stays aligned with project goals and launch requirements
