Bite-Size Kotlin Training

Course Overview

This remote training program is designed for teams who want to master Kotlin gradually over three months — without pulling your developers away from project work for a full week. The training follows a structured approach based on Kotlin Crash Course, covering fundamentals, object-oriented programming, collections, functional programming, coroutines, delegation pattern, and unit testing.

Each session includes practical exercises and real-world applications, so your team applies what they learn incrementally to your codebase.

What Your Team Will Be Able to Do

After completing this training, your developers will:

Write idiomatic, maintainable Kotlin code grounded in a deep understanding of the language fundamentals and best practices.
Eliminate null pointer exceptions by mastering Kotlin’s null safety techniques and avoiding common pitfalls.
Handle complex business logic confidently using control flow statements (if, when, loops) and structured error handling.
Process and transform data efficiently using Kotlin collections for filtering, sorting, mapping, and aggregation.
Design modular, reusable systems by applying object-oriented principles — classes, interfaces, and inheritance.
Write concise, expressive code using functional programming concepts including lambdas and higher-order functions.
Build responsive, non-blocking applications with coroutines for efficient asynchronous programming.
Simplify code architecture using the delegation pattern to reduce boilerplate and improve maintainability.
Ship with confidence by writing and running unit tests using Kotlin test frameworks.
