Build Once. Deliver Everywhere.Stop maintaining separate codebases for every platform. Modern Kotlin Multiplatform Development shows you how to build production-ready applications for Android, iOS, Desktop, and Web from a single shared Kotlin codebase using today's most powerful multiplatform technologies.Whether you're an Android developer expanding into cross-platform development or a Kotlin programmer looking to build scalable applications, this practical guide walks you through the complete development workflow. You'll learn how to organize shared business logic, create modern user interfaces with Compose Multiplatform, communicate with REST APIs using Ktor, manage local data, implement dependency injection, and apply Clean Architecture to build maintainable, testable applications.Rather than focusing on isolated concepts, this book demonstrates how the pieces fit together in a real-world project. You'll explore shared modules, coroutines and Flow, reusable UI components, platform-specific integrations, testing strategies, deployment techniques, and performance optimization. By the end, you'll have the skills and confidence to design, build, and maintain high-quality Kotlin Multiplatform applications that scale across multiple platforms.In this Book You'll Learn to:Build shared codebases for Android, iOS, Desktop, and Web using Kotlin Multiplatform.Develop modern cross-platform user interfaces with Compose Multiplatform.Integrate REST APIs with Ktor, manage local storage, and implement dependency injection.Apply Clean Architecture, shared business logic, testing strategies, and best practices for production-ready applications.Package, optimize, and deploy multiplatform applications with confidence.About the AuthorMax Wardo is a software developer and technical author dedicated to helping developers master modern programming technologies through practical, project-based learning.
