Refactoring legacy Kotlin code for null safety and immutability involves leveraging Kotlin's type system, safe-call operators, and data classes with copy() for immutable updates. This prevents null-related errors and improves maintainability.

To apply structured concurrency and DSL builders in Kotlin, use coroutines, Flow patterns, and DSL builders. This approach creates scalable, expressive APIs while ensuring robust asynchronous data handling.

You need sealed classes and extension functions in Kotlin when upgrading modules to embrace idiomatic hierarchies and extending class functionality without inheritance. They codify requirements for type-safe, maintainable Kotlin usage.

To identify common Kotlin anti-patterns during code review, check for improper null safety, misuse of data classes, and unstructured concurrency. Propose modern improvements using idiomatic patterns like sealed hierarchies and safe-call operators.

Yes, you can use Gradle Kotlin DSL conventions to refactor existing Kotlin modules. This upgrade embraces idiomatic Kotlin usage, applying null safety, data classes, and DSL builders to improve code quality and maintainability.

Using copy() for immutable updates in Kotlin data classes matters because it enforces value semantics and prevents unintended mutations. This strategy leverages Kotlin's type system for safer, more maintainable data handling.
