React Native is a popular JavaScript programming language framework used for mobile development; if we explain in simple words, a developer on React Native — a specialist who uses this platform to make applications for iOS or Android devices.

Let’s briefly list the responsibilities of a React Native programmer:

1. Creates the outer part of the program, with which the user interacts: images, content, buttons, forms, etc.
2. They configure dynamic and animated transitions, reactions to gestures (swipes) in the application.
3. They integrate the service with the camera, microphone, and GPS.
4. They configure push notifications and chats.
5. Programs fingerprint authorization, Face ID, e-mail, or social network authentication.
6. Adds the ability to pay via Apple Pay and Google Pay.
7. Performs code testing and debugging, looking for and fixing bugs.
8. Writes updates and optimizes an already running service.

What The Specialist Should Be Able To Do

Here’s what a developer should know and be able to do:

• program in the JavaScript language;
• have experience working with React Native, React.js, and Redux frameworks;
• use the tools to create iOS and Android programs — XCode and Android Studio;
• understand the principles of mobile development;
• know what kinds of app testing methods there are;
• have a good command of English while reading technical documentation;

The knowledge and skills of a React Native programmer depend on their qualifications. There are several levels in this industry — we will discuss each in more detail below.

Junior

Junior — is a beginner with six months of experience who works under the guidance of a more experienced colleague and solves only typical or simple tasks.

What a Junior developer should know:

1. JavaScript programming language. His code often has errors and overly complex constructions, so the mentor constantly reviews.
2. The main components of the React Native framework.
3. The Redux library for managing application state
4. The peculiarities of developing applications for Apple and Android smartphones and understanding the principles of UX/UI.
5. Practical ways to test code.

A junior should have at least one project of their own in their portfolio. The main task is to sharpen the skills, improve their qualification and continually educate themselves.

Middle

The middle is an experienced developer with at least two years of JavaScript development experience. His portfolio includes several projects done independently, and his code complies with programming standards and does not need to be verified.

What a Middle-developer can do:

1. Program unique options, such as camera or microphone operation, geolocation, etc.
2. Optimize the performance of different kinds of applications.
3. Store and cache data offline, work with other databases, and know when to use off-the-shelf code or create logic from scratch.
4. Set up integration with external services, such as Google or Facebook for account login, PayPal or Apple Pay for smartphone payment, etc.
5. Publish online services on Google Play and App Store.

Senior

A Senior is a professional with at least four to five years of experience developing React Native. He has in-depth knowledge of programming, JavaScript, Typescript, React Native, and many successful projects in his portfolio.

What a senior developer should be able to do:

1. Write code in JS and understand other languages used for mobile development: Objective-C, Kotlin, Java, and Swift.
2. Integrate their libraries and frameworks into programs created in React Native.
3. Set up continuous integration and continuous delivery.
4. Develop application architecture according to technical requirements and business goals.
5. Know object-oriented programming principles and design patterns.
6. The highest rung in the development profession is team lead. A team leader has the skills of a senior programmer and experience in team management: they can organize the workflow, estimate the project complexity and deadlines, distribute tasks between performers. In this case, the specialist needs knowledge of agile methodologies, such as Scrum.

Are Programmers With Knowledge of React Native in Demand?

Creating mobile applications in React Native has several advantages:

1. The program is assembled from integrated, adapted modules, so the development time is reduced, and the work cost lessens.
2. It is not necessary to write code for iOS and Android separately. The project runs using intermediate libraries, so the application works equally well on both operating systems.
3. It is easier to make improvements and corrections — updates are created for both mobile platforms at once. It is especially relevant for online services for which you need to get feedback from users quickly.
4. React Native is the basis for Instagram, Facebook, Skype, Airbnb, Pinterest, Discord, etc. From all of the above, we can conclude that React Native programmers are in demand, and the need for them will be steadily high as the number of smartphone applications increases every year.

To assess the current situation, we examined information on the HeadHunter website. Today, about 1,000 vacancies for specialists with knowledge of React Native have been published. Most employers are looking for candidates with about 3-4 years of experience, i.e., middle-level programmers. Developers are most in-demand in large companies.
