Learners will receive a Certificate of Completion from Uplatz, validating their expertise in Kotlin Multiplatform and cross-platform app development. This certification demonstrates readiness for roles in mobile development, cross-platform engineering, and full-stack development.

Kotlin Multiplatform skills prepare learners for roles such as:

• Mobile Developer (Android/iOS + KMP)

• Cross-Platform App Developer

• Full-Stack Developer (Kotlin-based)

• Software Engineer (Native + Multiplatform)

• Enterprise Application Developer

With adoption by JetBrains, Google, and global enterprises, Kotlin Multiplatform is becoming a key technology for cross-platform efficiency and scalability.

1. What is Kotlin Multiplatform?
   A technology for sharing code across multiple platforms while retaining native performance.

2. How is KMP different from React Native or Flutter?
   KMP focuses on shared business logic with native UI, while others enforce custom UI frameworks.

3. What are expect/actual declarations in KMP?
   A mechanism to declare common APIs with platform-specific implementations.

4. What libraries are commonly used with KMP?
   Ktor (networking), SQLDelight (databases), Kotlinx Serialization (data handling).

5. How does concurrency work in KMP?
   Through Kotlin Coroutines, enabling consistent async programming across platforms.

6. Can KMP be used for iOS development?
   Yes, KMP integrates with Xcode, allowing shared logic with Swift UI.

7. What is the benefit of shared modules?
   Reduced code duplication, faster development, and easier maintenance.

8. How does KMP handle UI development?
   UI remains platform-specific (SwiftUI, Jetpack Compose), while logic is shared.

9. What are challenges in adopting KMP?
   Tooling maturity, debugging across platforms, and developer onboarding.

10. Where is KMP widely used?
    In SaaS apps, enterprise applications, and cross-platform mobile projects.
