Have been a long time follower (and big fan) via Medium and love your Udacity course reviews. It is good to see how your learning has finally amounted to something (I can certainly see you are committed to learning both ML and web development).
It is also inspiring to see how if you committed to learning, you will eventually build something of your own!!
Just tried out the two documents mentioned which is really interesting and insightful.
Keen to see how the product performs when my semester reopens, with "real" lecture notes and textbook!
Keep it up!
