Tell us about your experience developing in Kotlin and large projects where you used this language.

I have used Kotlin in several Android projects of varying scales. For example, in a large e-commerce application, I was responsible for developing user interface modules and business logic, using Kotlin to improve readability and reduce boilerplate code.

Kotlin allowed me to effectively utilize coroutines for asynchronous operations, which enhanced the app's responsiveness. I also used extensions and DSLs to simplify working with UI and configurations.

In another project related to data processing, Kotlin helped integrate the language's functional features, such as collections and lambda expressions, which sped up development and improved code quality.
