How to Hire Kotlin Developer in 2023: A Comprehensive Guide

Kotlin is a new universal programming language designed to make mobile app development easier and more efficient. It is a cross-platform, statically typed language with full compatibility with Java. 

Kotlin was designed to improve coding productivity and code safety. There are around 4.86 million Kotlin developers in the world already. Most of these are Android app developers.

Kotlin is one of the top ten fastest-growing programming languages, according to Github. It avoids common mobile application mistakes.

Google announced Kotlin as the preferred language for Android application development, contributing to its growth.

What Is The Purpose Of Kotlin?

Kotlin is an open-source language that runs on the JVM and is fully compatible with Java. 

Kotlin was first designed primarily for Android devices, but its community grew, and it now offers a diverse set of applications.

Android development

Kotlin was first released for Android devices, allowing developers to write simpler, more secure code. 

Android Studio was the first Kotlin IDE, allowing you to implement code completion and type checking like Java does.

Back-end web development

Kotlin makes server-side web development much simpler than Java. Because Kotlin is a current programming language, it includes new features that allow web developers to design scalable applications. 

Full-stack web development

Full-stack developers simply need to be familiar with Kotlin, and they will produce front-end code in the same language they used for the back-end, which will be compiled into JavaScript and run in the browser.

Data Science

Data Scientists can use all of the standard Java libraries that they are familiar with in Java projects, but their code must be written in Kotlin. 

Data scientists employ Kotlin libraries for data visualization and experimental research in their projects.

Where to Hire Kotlin App Developers?

Freelancer 

They are contract workers that work as a self-employed individual. If your project is short-term and you have a limited budget, you may want to consider hiring a freelance Kotlin developer. 

Freelance developers can be found on websites like Freelancers.com, Upwork, LinkedIn, and others.

In-house developer

In-house development necessitates the formation of a strong team from the start. Companies hire full-time employees based on the abilities required to create their teams. 

In-house workers are somewhat motivated as they come to the office and engage with colleagues. In-house personnel can be hired by posting job openings online. 

With all of these layoffs and the recession, posting a job opportunity may help you attract qualified developers.

Outsourcing

Outsourcing is a commercial technique whereby businesses contract a third-party service provider to complete a task. They are not part of the in-house team but are easily traceable. 

Outsourcing might be risky, but if you choose your outsourcing Kotlin app development company carefully, you will be safe. Outsourcing also allows you to select developers from all over the world.

Advantages Of Kotlin

Because of the many advantages that Kotlin offers its users, Google has begun to promote it as their preferred language for mobile app development. 

As a result, anytime you hire an Android developer, you must ensure they can design apps in Kotlin. 

Less coding required

Most Kotlin developers like how little coding is required to create an application in Kotlin. Because a Kotlin app requires less coding, the app’s speed in the market is greatly decreased. 

Reduced time-to-market results in significant cost savings. Kotlin enables developers to build code that is both small and concise. 

According to research, Kotlin code has 40% fewer lines than Java. Furthermore, Kotlin allows developers to simply adjust the code.

More protected

Program security is essential for any program, whether it’s an Android or an iOS app. 

Kotlin is a secure framework that eliminates device crashes and misconfigurations that can occur in an application due to coding flaws. 

Immutability and null safety have been improved in Kotlin. Kotlin enables programmers to create more stable applications.

Open-source language

Because Kotlin is an open-source programming language, no license fees are associated with it. Furthermore, because it is open-source, the platform attracts many developers from all over the world. 

An open-source platform also helps expand by creating a robust community of developers who want to contribute to an open-source platform.

Google support

Google has given Kotlin its full support. Google declared in 2019 that Kotlin is the preferred language for developing Android apps. Google stated that it would first provide new features and APIs to Kotlin. 

The key reason for Google’s backing for Kotlin was its potential to allow developers to achieve the same outcomes with less code.

Compatible

One of the unique characteristics of Kotlin that makes it a standout performer in the business is its compatibility. 

Kotlin is a language that may be used for both client-side and server-side development. Aside from that, Kotlin may be used to create mobile and web-based apps.
