Kotlin Multiplatform solutions

With the help of KMP, we share common code between mobile and web apps, and write platform-specific code only where it’s necessary. It helps us to ship features faster, increase efficiency, and decrease costs by 30%. All this without compromising on the quality of user and developer experience.
