Implement extensions and DSLs for concise code

Optimize collections and performance with advanced lambdas

Develop robust Android apps with Kotlin Multiplatform

Manage null safety and smart casts in real projects

Integrate Kotlin into modern MVVM architectures

Training program

Module 1Null Safety and Smart Casts in Kotlin: IntelliJ tools, practical exercises

Dive into null management with the Elvis operator and safe calls, practice refactoring Java code to secure Kotlin, complete exercises on smart casts to avoid crashes, produce infallible functions ready for your Android apps, and boost productivity from day one.

Module 2Higher-Order Functions and Lambdas in Kotlin: functional methods, real-world cases

Explore lambdas with receiver, function chains like map and filter, apply them to real datasets for sorting and transforming data, code interactive examples with live coding, generate reusable utilities that speed up daily development, and experience the power of functional programming.

Module 3Kotlin Coroutines: async/await, flow management, asynchronous deliverables

Start coroutines with launch and async, manage suspensions for non-blocking APIs, implement flows for real-time data streams, test on mobile use cases like network requests, produce a production-ready coroutine module, and master asynchronous without hellish callbacks.

Module 4Extensions and DSLs in Kotlin: custom builders, design tools

Create extensions to enrich standard classes, build fluent DSLs for HTML or JSON, apply them to complex configs, practice in pairs on mini-projects, deliver copy-paste snippets for your teams, and transform verbose scripts into poetic, maintainable code.

Module 5Kotlin Multiplatform Projects: Android/iOS, MVVM integration, certification

Assemble everything into a fullstack multiplatform project with KMM, integrate Room and Retrofit in Kotlin, deploy a complete MVVM app, debug in groups with coach feedback, finalize a certified portfolio, and leave with skills that multiply your devops and mobile opportunities.
