What to know before hiring React Native Developers

React Native is a popular open-source framework developed by Facebook that allows developers to build cross-platform mobile applications using JavaScript and React. It enables the development of native apps for both iOS and Android with a single codebase, making it a cost-effective solution for companies looking to launch apps across multiple platforms. Hiring the right React Native Developer is crucial to ensuring the success of your mobile app.

Here’s what you need to know to effectively hire React Native Developers for your team.

What does a React Native Developer do?

A React Native Developer specializes in building mobile applications that work seamlessly across both iOS and Android using a single codebase. Their primary responsibilities include:

• Developing cross-platform mobile applications: React Native Developers write reusable code that works on both iOS and Android devices, ensuring that apps function similarly across platforms.
• Building native-like user interfaces: React Native Developers are responsible for creating smooth, responsive, and intuitive UIs that mimic the look and feel of native apps.
• Optimizing app performance: They focus on optimizing the app’s performance to ensure fast load times, smooth animations, and efficient memory usage across different devices.
• Integrating APIs and services: React Native Developers connect front-end components with back-end services, third-party APIs, and native modules, ensuring smooth data flow and integration with the app.
• Collaborating with designers and back-end developers: React Native Developers work closely with designers to implement visually appealing and functional interfaces and with back-end teams to ensure seamless API integration.
• Handling platform-specific nuances: React Native Developers ensure that apps account for platform-specific differences (e.g., navigation, gestures, performance optimizations) between iOS and Android.

React Native Developers are crucial in building high-performance, scalable mobile applications for both iOS and Android platforms with a single codebase.

How to hire React Native Developers: a quick guide

Define your requirements

Before hiring a React Native Developer, it’s essential to define your project’s scope and requirements clearly. Knowing what you need will help you find the right developer with the relevant skills and experience. Consider the following:

• App complexity: Are you building a simple utility app, a game, or a complex enterprise-level application? The complexity of your app will determine the level of expertise required.
• Integration with native features: Will your app require access to native device features (e.g., camera, GPS, notifications)? If so, ensure the developer is experienced with integrating React Native apps with native modules through bridges.
• Cross-platform consistency: Do you need your app to behave consistently across iOS and Android, or do you want platform-specific features and optimizations? Developers should be adept at handling platform-specific code when necessary.
• API and back-end integration: Does your app need to interact with external APIs or databases? The developer should have experience with API integration, handling data flow, and ensuring secure communication with back-end services.
• User interface and experience: If your app has specific design requirements, make sure the developer can convert high-fidelity design mock-ups into functional, pixel-perfect mobile interfaces.
• Performance and optimization: Will your app handle a large user base or need to perform well under high traffic? The developer should be skilled in optimizing React Native apps for performance and memory usage.

Clearly defining these requirements will help you narrow your search and find a React Native Developer with the right expertise for your project.

Where to find React Native Developers

There are several platforms where you can hire top-tier React Native Developers. Job boards like LinkedIn, Indeed, Jobshark, and Glassdoor are excellent starting points. Additionally, platforms like Toptal, Jobshark, Upwork, and Fiverr offer access to freelance React Native Developers. 

Engaging with React Native-focused communities on GitHub, Stack Overflow, or Reddit can help you connect with developers who are actively contributing to the ecosystem. Attending or sponsoring events like ReactConf or local React Native meetups is another way to network with skilled developers.

For quicker hiring, partnering with tech sourcing companies, like Jobshark, can help streamline the process.

Assess technical skills

When hiring a React Native Developer, evaluating their technical skills is essential to ensure they can deliver a high-quality app for both iOS and Android platforms. Key technical skills to assess include:

• Proficiency in JavaScript/TypeScript: React Native is built on JavaScript, so a strong understanding of modern JavaScript (ES6+) is crucial. Many developers also use TypeScript for added type safety and cleaner code.
• Experience with React: React Native is built on React, so the developer should be proficient in React concepts such as components, JSX, props, state management, and lifecycle methods.
• Understanding of Native Mobile Development: While React Native allows developers to write code for both platforms, some apps require platform-specific features. Look for developers with experience in native iOS (Swift/Objective-C) or Android (Kotlin/Java) development when needed.
• State Management: React Native Developers should be experienced in state management libraries such as Redux, Context API, or MobX to handle complex application states.
• API integration: The developer should be proficient in working with RESTful APIs or GraphQL, using tools like Axios or Fetch to integrate backend services with the mobile app.
• Version control: Familiarity with Git or other version control systems is essential for managing code, especially when working in a team.
• Testing and debugging: Experience with testing tools such as Jest, Mocha, or Detox is important for ensuring the app’s functionality and performance across multiple devices and platforms.
• App Store and Google Play submission: Ensure the developer is familiar with the processes for submitting apps to the App Store and Google Play Store, including understanding the specific guidelines for each platform.

You can assess these technical skills through coding tests, reviewing code samples, and conducting technical interviews to ensure the developer is well-suited for your project. You can also use platforms like DevSkiller, Codility, HackerRank, or LeetCode to assess technical skills.

Evaluate soft skills and cultural fit

Some soft skills to look for when hiring a React Native Developer include:

• Communication: Effective communication is essential, especially when working with designers, backend developers, or stakeholders. A good React Native Developer should be able to explain technical concepts clearly and keep you updated on progress.
• Problem-solving ability: React Native Developers often face challenges related to performance optimization, cross-platform compatibility, and API integration. A strong problem solver can quickly identify and fix issues that arise during development.
• Collaboration: If your team follows Agile or Scrum methodologies, look for developers who are comfortable working in sprints, participating in daily stand-ups, and contributing to code reviews.
• Adaptability: React Native and its ecosystem are constantly evolving. A great React Native Developer should be open to learning new tools, libraries, and frameworks to stay up-to-date with the latest trends and best practices.
• Attention to detail: A skilled React Native Developer should be able to implement pixel-perfect designs and ensure the app’s UI is functional and visually appealing on iOS and Android devices.

Evaluating these soft skills through interviews and trial projects can help ensure the developer integrates well with your team and project goals.

A brief history of React Native

React Native was created by Facebook to solve the problem of developing separate codebases for iOS and Android. Here’s a brief look at its evolution:
