Hello everyone, and welcome to the Complete Kotlin Course: Zero to Job-Ready!
My name is Andrey Sumin.
This course is for anyone who wants to learn Kotlin—a modern language used to build Android apps, create server-side applications, and work on multiplatform projects. It’s designed so you can start from scratch, even with no prior programming experience. Not just the basics—we’ll dive into the language’s nuances and practice hands-on, so by the end you’ll be fully prepared for a Kotlin interview. Throughout the course, you’ll complete practical assignments and projects that reinforce each topic and help you build real development skills.
I wish you success in mastering Kotlin—may you gain new knowledge and the inspiration to conquer the world of programming! See you in the course!
Why Kotlin?
Because it’s a modern language with official support from Google. Designed with lessons from dozens of other languages, Kotlin keeps the best practices and removes unnecessary complexity. Code is shorter and clearer, and writing in Kotlin is fast and convenient. Built-in null-safety and a modern concurrency model with coroutines improve application stability and safety. Plus, it’s fully compatible with Java and the JVM ecosystem, so you can leverage existing libraries and familiar tools without extra hurdles. Most importantly, Kotlin has strong prospects: active development, broad industry support, and high market demand.
