What is Kotlin?
Like most of the other popular technologies and platforms, Kotlin is also an open-source programming language. The Kotlin website describes it as ‘A modern programming language that makes developers happier.’ It must be doing much more than making developers happier; else, it could not have sustained the fast growth it has had in a short time.
It enables sharing of the code between multiple mobile platforms, is familiar with the JVM-based web technology, and enables server-side and front-end development. It is also a concise and safe programming language, which is easy to learn. The ability to build powerful applications fast using Kotlin is another reason for its popularity. Existing applications can be easily made cross-platform using Kotlin, which is why most businesses are exploring this opportunity. One of the most appealing things about open source is the huge community that enables support, and Kotlin is no less. Extensive resources and a rich ecosystem of community libraries are just one part of the Kotlin developer support system.
Even though the Kotlin syntax is not compatible with Java, it still is interoperable with it. The Kotlin IDE even comes with a Java to Kotlin converter, making adoption and conversion easier. Also, Kotlin addressed many known Java issues, which is why it is popular among developers. Additionally, Kotlin is supported by most major Java IDEs like NetBeans, IntelliJ IDEA, Eclipse, and Android Studio. Kotlin syntax is user-friendly and intuitive, making coding in it easily reviewable. Also, being modern, Kotlin strives to be concise, so Kotlin developers can write less code to achieve more. Code optimization and removal of redundancy, two main concerns of developers, can be addressed easily in Kotlin. This translates to increased productivity, less budget, and save on the most important aspect of the Agile development environment - Time.
Kotlin developers enjoy a significant amount of flexibility, and the first-class support makes coding even more enjoyable. Kotlin allows for object-oriented and functional constructs, and it solves real-time issues during coding, which is a significant advantage.
Kotlin development concepts
Kotlin developers should have an IDE installed to get going with Kotlin programming on their system. The complete guide on the installation and getting started is available as documentation on the Kotlin official site. There are also tutorials with examples and materials such as books and other EduTools available for aspiring Kotlin developers. They have also listed some YouTube channels which have informative resources that can be referenced.
Once the Kotlin project is created, it can be built using build tools Gradle, Maven, or Ant, and Kotlin release is shipped with a standalone version of the compiler. This is done manually through the command-line interface. But if you are using any of the supported IDEs, then the Kotlin project may also be compiled using the IDE compile or Run button. Kotlin developers can use TeamCity to build their Kotlin project if it is set up as required. Finally, Kotlin developers should use KDoc for documentation of Kotlin code, and the corresponding document generation tool is Dokka.
Kotlin and Android Development
It took a while for Android developers working with Java to shift to Kotlin as a programming language. The flexibility, ease of use, and the fact that Kotlin addressed the issues they faced while programming in Java helped. Kotlin compilers are very efficient and perform multiple checks that ensure fewer errors in codes and more minor bugs to fix, making it more robust. Kotlin developers become highly versatile because of the many features and advantages of the Kotlin language and the support provided by the open-source community.
Kotlin code is safer as compared to Java as it consistently focuses on addressing vulnerabilities. Also, Kotlin and Java codes can coexist on Android, and it’s very easy to migrate Java code to Kotlin. Google will follow a Kotlin-first approach which means new Android development tools or content will be designed keeping Kotlin in mind. Perhaps, all these also explain why over 60% of professional Android developers use Kotlin.

Experience
Kotlin developers are a much-in-demand breed as its popularity is growing by the day; it is one of the fastest-growing programming communities in the world currently. Knowledge of Kotlin improves a mobile app developer’s saleability. Since it is easy to learn, many organizations are willing to train people also. Most junior Kotlin developers have little programming experience, yet it helps them pick up and deliver Kotlin apps. At senior levels, Kotlin developers have a strong background of having worked with Java and Android-based development. They have a complete understanding of the mobile app ecosystem, including front-end, back-end, and various emerging technologies. Therefore, it is easier for them to guide the juniors on the multiple aspects of evaluating technologies and the programming approach to ensure optimized code.
- Total project ownership with involvement from planning, design, coding, testing, and deployment.
- Guiding junior Kotlin developers to ensure the best use of available Kotlin resources.
- Critical thinking, analytical approach to problem-solving, and effective stakeholder communication management.
- A good understanding of the vision and mission of the business, its products and services, and user base to ensure that the apps meet the required standards.
Salary Structure
The salary structure of Kotlin developers depends on their technical skills and experience as it is a versatile programming language. Junior Kotlin developers can work independently on assigned Kotlin app modules or even the complete app, depending on the nature of the project and the team size. At senior levels, Kotlin developers can manage the complete plan, build and release of the various versions of the app based on user requirements and feedback. We at Skuad can help you hire the best Kotlin developer talent in the industry, tailored to meet your requirements.
