Kotlin Coroutines and Channels
Write asynchronous code like a professional—with suspending functions, structured concurrency, and a real-world GitHub project that works across threads.
About this course
Modern apps rely on asynchronous programming, and Kotlin’s coroutines are built for it.
This hands-on course teaches you to write clean, responsive code with coroutines and channels: avoiding blocked threads, managing concurrent tasks, and sharing data safely.
You’ll upgrade a GitHub contributor aggregator from a blocking setup to a fully concurrent system, mastering suspending functions, structured concurrency, cancellation, and real-time progress tracking. You’ll also learn to use channels to coordinate coroutines without locks or callbacks.
Your result: a working GitHub API integration built from scratch using modern Kotlin concurrency patterns, plus the confidence to apply these skills in Android, backend development, and beyond.
