Kotlin Patterns

This is a comprehensive reference for writing idiomatic Kotlin that goes beyond basic syntax. It covers the patterns that make Kotlin code actually feel like Kotlin: null safety with Elvis operators instead of force-unwrapping, sealed classes for exhaustive when expressions, structured concurrency with coroutineScope and async/await, and type-safe DSL builders. The examples are practical, showing things like modeling API errors with sealed interfaces and using value classes for zero-overhead type safety. Use this when you want your Kotlin to look like it was written by someone who understands the language's strengths, not just Java with different keywords.
