One Codebase, Every Platform: Kotlin Multiplatform in Production: Sharing Business Logic Across iOS, Android, and Web

By RICHARD BOOZMAN

Building applications for multiple platforms often means maintaining multiple codebases.

The result is duplicated logic, inconsistent behavior, slower development cycles, and higher maintenance costs.

"Kotlin Multiplatform in Production" is a practical, engineering focused guide to building cross-platform applications with shared business logic using Kotlin Multiplatform.

This book teaches you how to maximize code reuse while preserving the native experience users expect on every platform.

Why Kotlin Multiplatform matters

Modern teams must support:

iOS applicationsAndroid applicationsweb experiencesbackend services

Maintaining separate implementations for every platform can quickly become expensive and difficult to scale.

Kotlin Multiplatform allows teams to:

share core business logicreduce duplicated codeimprove consistency across productsaccelerate feature deliverymaintain platform specific user experiences

This book shows how to achieve these benefits in real production environments.

From separate apps to unified engineering

Throughout the book, you will learn how to:

design maintainable shared modulesreduce duplication across teamsbuild reusable domain and data layersintegrate platform specific capabilities cleanlyimprove development velocitymaintain production quality across platforms

Each chapter focuses on practical software engineering workflows used in modern cross-platform teams.
