Design Patterns in Kotlin: Complete Guide and Professional Practices for Scalable Architecture, Modern Kotlin Apps, and Clean Code Design (Mastering Kotlin Development Series)

Master the Craft of Modern Kotlin Development with Scalable Architecture, Clean Code, and Proven Design Patterns

Whether you're building microservices with Spring Boot, APIs with Ktor, or architecting cross-platform Kotlin apps, this comprehensive guide delivers everything you need to write professional, maintainable, and scalable software using modern Kotlin.

Design Patterns in Kotlin offers a practical, expert-level exploration of the design patterns and architectural principles used by top-performing software engineers and teams. This is more than just a reference—it’s a hands-on blueprint for crafting production-grade Kotlin systems aligned with industry best practices.

• Implement creational, structural, and behavioral design patterns the idiomatic Kotlin way

• Build scalable architectures using Clean Architecture, Hexagonal Architecture, and CQRS

• Leverage coroutines, Flow, and structured concurrency for high-performance backend systems

• Apply patterns in real-world projects using Ktor and Spring Boot frameworks

• Create testable and modular code with Repository, Service, and Use Case abstractions

• Avoid common anti-patterns and legacy design traps that slow down development

• Follow practical examples of domain-driven design, dependency injection, and microservice patterns

Each chapter includes up-to-date, well-documented code examples and implementation strategies based on real-world use cases. Every function, class, and pattern is carefully explained—ideal for Kotlin developers who want to confidently build apps that scale.
