Description of the Kotlin Training Course
Kotlin, developed by JetBrains and officially supported by Google, is establishing itself as the language of choice for modern Android applications.
But Kotlin isn’t just for mobile: it’s a cross-platform language capable of targeting the backend (Ktor, Spring), the web (Kotlin/JS), or even native (Kotlin/Native).
This Kotlin training course gives you a solid foundation for coding efficiently in Kotlin, whether you’re starting an Android app, a microservice or a cross-platform tool, thanks to its concise, safe and expressive syntax.

Format
Remote (recorded sessions).
GOOD TO KNOW
This training course includes numerous exercises (60% practical) to enhance learning. Each session will take place even if only one person is registered (except in cases of force majeure). A preliminary interview is held between the participant and/or a company representative in order to fully assess the participant’s profile (level, needs, professional context, challenges, etc.).
Assessment : during the training course, the trainer assesses the participants’ progress through multiple-choice questions, role-playing exercises and practical work. Participants receive a certificate of completion at the end of the training course.
This training course is part of our Development Training Courses. Explore our other development trainings to design modern, performant and maintainable applications.
objectives of this Kotlin Training Course
By the end, each participant will be able to :
- Understand the fundamentals of the Kotlin language.
- Write code that is more concise, expressive and secure than in Java.
- Master null safety, lambdas, extensions and data classes.
- Use Kotlin collections and higher-order functions.
- Structure an Android or backend application with Kotlin.
- Be ready to code for Android, backend, or cross-platform projects.
Prerequisites
- Knowledge of an object-oriented language (Java, C#, Swift, etc.)
- Installed development environment (Android Studio or IntelliJ)
- Familiarity with mobile or server programming desirable (but not essential)
- Because each participant has a unique background and expectations, a preliminary interview with our expert allows us to precisely identify their objectives, level and professional challenges.
This enables us to tailor the training content to ensure relevant and personalised learning.
Target Audience
This Kotlin training course is designed for Java, Swift, Python or JS developers who want to increase their productivity with a modern and powerful language.

FAQ – Kotlin Training
What is Kotlin?
Kotlin is a modern, concise and Java-interoperable language developed by JetBrains, now Android’s official language. It runs on the JVM, natively (Kotlin/Native) and cross-platform (Kotlin Multiplatform). At MFE-IT, the training helps you master the syntax, functional programming, concurrency (coroutines) and architectural best practices.
What is the difference between Kotlin and Java?
Kotlin offers more concise syntax, built-in null safety, extensions, pattern matching with when, data classes and coroutines. It is 100% interoperable with Java, enabling progressive migration. MFE-IT also shows how to combine both languages in the same project.
Is Kotlin only used for Android?
No. Kotlin is widely used on the server side (Ktor, Spring Boot), in scripting, desktop development (Compose Multiplatform), and for iOS/web apps via Kotlin Multiplatform. The MFE-IT training covers backend and mobile use cases in a balanced way.
How long is the Kotlin training at MFE-IT?
The training lasts 5 days (35 hours), remote or on-site. An intensive format, highly practice-oriented, with progressively demanding exercises.
