Refactor Kotlin code by applying safe access patterns, replacing mutable state with immutable data classes, and using sealed hierarchies to model domain data correctly and avoid runtime null errors.

Structured concurrency with Kotlin coroutines and Flow is implemented by applying specific patterns for asynchronous operations, ensuring coroutines are scoped properly to prevent leaks and manage lifecycle correctly.

Build type-safe DSLs in Kotlin by utilizing DSL markers to prevent scope leakage, combining extension functions and delegates to create fluent, structured configuration interfaces that enforce compile-time safety.

Use Kotlin sealed classes and value wrappers to model domain data correctly by representing restricted hierarchies, enforcing immutability, and ensuring exhaustive when-expressions compile-time safety.

Gradle Kotlin DSL configuration requires idiomatic patterns to standardize project setup, leveraging Kotlin's type-safety and extension functions to create maintainable, programmable build scripts.

Use Kotlin delegates and extension functions during module refactoring to standardize code patterns, reduce boilerplate, and add behavior to existing classes without inheritance, improving maintainability and readability.
