Learn Kotlin for Android and backend: null safety, classes, collections and coroutines, with a 1:1 mentor at your pace.
Free, no-obligation chat · Affordable plans that fit your budget · Start this week
About this course
Kotlin is the preferred language for Android development and is also used for backend services with Spring and Ktor. It is concise and safe, but learners new to it often find null safety, lambdas, data classes and coroutines confusing at first.
This course follows the official Kotlin documentation and standard training path: basics, control flow, functions, classes and objects, null safety, collections and lambdas, interfaces and inheritance, extension functions, coroutines and testing. Each module lists topics and what you will be able to do at the end.
Learn with an affordable 1:1 mentor who explains each idea with short examples and reviews your code with you. Self-study lessons on MentorNxt exist only for Java and Python, so this course is taught in live 1:1 sessions. Message us on WhatsApp or email, or fill in the short form, for a free, no-obligation chat. We will suggest a plan that fits your budget and flexible timings, and you can start this week.
