Kotlin
The modern JVM language, official for Android development.
Kotlin is Google's recommended language for Android: interoperable with Java, more concise and safer (null-safety, coroutines). Beyond mobile, it also serves server-side (Ktor, Spring) and cross-platform via Kotlin Multiplatform.
What Kotlin brings to your project.
Typical use cases: Native Android applications, JVM backends, shared multiplatform code.
- 01
Null-safety and strict typing: fewer production crashes.

Coroutines: readable and structured async concurrency.

Jetpack Compose: modern declarative Android UI.
