Hire React Native Developers

Built upon Facebook’s JavaScript library React for web development, React Native is used for mobile app development. As the greater part of the code can be shared between platforms, React Native enables cross platform app building, in other words, you can simultaneously develop an Android app and an iOS app. This allows for native app development for the new teams of developers and also lets existing native apps development teams work faster, thus streamlining the entire development process.

Like React for web apps, React Native employs a mixture of JavaScript and XML-esque markup and triggers the native rendering APIs in Objective-C (for iOS) or Java (for Android). As a result, a React Native mobile application renders using mobile UI native components instead of webviews, and looks like any other mobile application. In addition, a React Native app can access features like a phone camera or user’s location.

React Native apps are not the same as web apps. A React Native iOS or Android app is running on mobile devices, and can’t load over the browser. Plus, neither of them is a hybrid app: it’s a genuinely native app built in JavaScript with the native components.

To hire a React Native developer who will bring the most value to your app development team, you should be able to identify whether they possess the required skills, both professional and interpersonal.

Outstanding technical knowledge is what makes a difference between the expert React Native developer and someone who still needs to do more learning of React Native app development. Here are a couple of skills every candidate on this job should master.

• Excellent knowledge of JavaScript. When you hire React Native developers, make sure they have deep knowledge of JavaScript. It is the heart of everything in cross-platform mobile app development. Your potential candidate for this position must know how to build components, how to structure the application logic and services, and understand their flow.
• Knowledge of basic React assumptions. The concepts like Virtual DOM, JSX, and component lifecycle should be as familiar to Native React app developers as treble clefs to the musician. Checking the applicant’s understanding of these terms is a must.
• Experience with Android and iOS development. Skilled React Native developer gets the difference between iOS and Android mobile app development. Being familiar with Objective-C and Swift in order to make the app work on different devices is also necessary.
• Familiarity with useful tech tools. You can’t demand from the person to know everything there is about software development, but it’s going to be a big plus if they are familiar with at least some extra tools like Redux, Enzyme, Hockeyapp, and so on.
• Writing clear code. The apps created by your development team should have a consistent and readable source code. This is important because you need to be able to easily maintain the app at present and make improvements in the future.

Your React Native developer is not going to work alone, so when you hire React Native app developers, make sure they are both great experts and nice people to be around, especially when you hire them for a full-time position. They should be good communicators, team players, problem-solvers. They also should be able to give constructive feedback, receive criticism, and generally be open-minded and curious folks.

Finally, make sure you only hire people that fit your company culture. You can find the best React Native developers in the world, but it’s not going to work if the team members don’t understand one another and don’t feel comfortable in each other’s company. Save yourself the hustle of having to reassemble the team all over again.

Here’s a small template you can use as a reference.
