A few words about Kotlin?

Kotlin is a cutting-edge programming language created to be clear, expressive, and compatible with Java code already in use. Since its introduction, Kotlin has grown in popularity as a flexible language with several benefits for app development. It has been a favorite among developers for creating reliable and effective applications due to its clean syntax and smooth integration with Java. Embracing the power of Kotlin opens doors to a host of exciting possibilities for modern software development. Kotlin provides the tools and capabilities to turn every idea into reality. Railwaymen is committed to helping you make the most of this language to ensure the success of your projects from the start.

The reasons why Kotlin is worth using

Kotlin’s value lies primarily in its ability to integrate seamlessly with Java. This makes it easy for developers to use the knowledge they’ve gained and the resources they have, while discovering more innovations. Compatibility in the case of Kotlin can be seen in different types of applications, both for Android development and server-side solutions. Kotlin is not just a programming language, but a versatile solution that allows developers to design efficient and, in addition, modern applications.

Why businesses are implementing Kotlin?

Enhanced Productivity

Developers may create more expressive code with fewer lines of code using Kotlin’s short syntax and contemporary features, which boosts productivity and shortens development cycles.


Kotlin’s compatibility with Java makes it simpler for businesses with existing Java codebases to embrace and integrate Kotlin without having to completely rebuild their old code.

Safety and Reliability

The expressive type system and null safety features of Kotlin help to lower frequent programming errors and improve the overall stability of projects.

Improved Readability

Developers can more easily understand and work together on projects because of Kotlin’s clear and simple syntax, which improves code readability.

Community Support

The Kotlin community, which is expanding, offers a plethora of information, libraries, and tools to help developers with their projects, making the development process more effective.

What might be the determining factor in using Kotlin in a project?

Concise syntax

Simplifies code development by reducing the number of unnecessary templates, allowing developers to present their concepts with fewer lines of code. It also has a direct impact on greater readability and maintainability of code, making Kotlin the preferred choice for projects where clean and efficient code is a priority.

Type system and null safety

These factors guarantee strong compile-time checks to detect type-related errors in the early stages of development, resulting in fewer failures at runtime. Null safety features, such as nullable and non-nullable types, help prevent null pointer exceptions by enforcing safe handling of null values, ensuring code reliability and reducing common programming errors.

Extension functions

Allow developers to extend existing classes with new functions without modifying their source code. This promotes a more modular and reusable code base, allowing the creation of utility functions that can be applied to different types of data, and making code easier to organize and maintain.

Which projects is Kotlin suitable for?

Because of its adaptability and strong features, Kotlin is a fantastic choice for a variety of applications. It excels at building apps for Android devices, and Google even supports it in this effort. It is ideal for creating Android apps that are full of features and effective due to its streamlined approach to writing code.

Kotlin also works well for building the back-end components of websites and online services, giving them the ability to handle numerous activities without stuttering. It can make it easier for developers to construct apps that function on a variety of gadgets, including PCs and smartphones.

In addition, Kotlin is employed in a variety of fields, including data analysis, game development, and even the construction of components for the “smart” devices we use on a daily basis. Thus, Kotlin is a versatile tool that may help you realize your ideas in a way that is user-friendly, whether you’re considering creating your own app, managing a website, or working on something completely different.

Overall, I really liked their management and after viewing their portfolio, they seemed very capable of doing what I wanted. Also, they were very supportive of the project itself, which was important to me. More than just being willing to do it, they understood what I was trying to achieve and were keen on helping me obtain my objectives.

I’m very fortunate to have the partnership that I’ve had with them. Their team appreciates that we’re a startup and privately-funded project. I’ve received tremendous amounts of work compared to the amount of money I’ve given them.

We did this in very short time even we had a lot of obstacles. Building the base in very professional way and as per the standard with the alignment of the up-to date technology helped us to start another project with them (KIOSK “self-service”) in very short notice and finished it as planned.
