Hello Brad!
I'm a junior developer from South Korea and i've been watching your video for about 2 years. ☺️
2 years ago I started to teach my self computer languages and how to build web app with your contents. They were my best teachers really.
Thank you so much for the amazing videos. ‼️
I want you to know there is at least one huge fan of you in Korea 😆
