The Powerful Android Apps with Jetpack Architecture has to be the best android course that I have ever learned. I have been a android developer for 5 years and iOS developer for 2 years but I have never made the jump to android architectures or got into jetpack that much. The courses in this site helped me grow my knowledge on design patterns and the android framework as a whole. Definitely looking forward to the courses that mitch has in store for us and hopefully I can get a high caliber mobile dev job which will put the skills I learned from these courses to good use.
