I've been an Android developer for about 6 years and I can definetly say that Mitch's materials (blogs, videos and courses) are one of the best contents you will find, even the free courses. I really enjoy Mitch's teaching style and he helped me a lot understanding some complex subjects such as Dependency Injection, Dagger, Hilt, RxJava Coroutines, MVVM and a lot more. Keep up with the awesome work man :)
