Complete Kotlin Design Patterns masterclass from Udemy

Kotlin is the main development language for the Android system.

Knowing how to build well structured programs and apps, that are scalable and robust is essential for every developer.

That's why I've created this course on Design Patterns for Kotlin.

Here you will learn how to apply popular patterns to your code, such as Builder, Adapter, Abstract Factory, as well as lesser known but very useful patterns, such as Composite, Decorator, Strategy etc.

This course will teach you how to structure your code so that it is more maintainable as it grows, and that it's easier to debug and test. When building a new project, you are not trying to reinvent the wheel, but instead to implement the correct solutions to the problems that you encounter.

It will also teach you the terminology that you need when you communicate with top level developers. When they say they implemented a factory for a piece of code, or the added a builder pattern for the creation of a certain object, you will immediately know what they mean.

This course covers 3 types of design patterns

Creational
Structural
Behavioural

We will also include code samples at each step of the way, so that you already know how to implement these patterns in practice.
