I like how you're giving yourself a solid goal and plenty of time to achieve it.
Quick question - you mention that you'd like to build an MVP yourself, do you know what product you'd like to build or what market you're interested in serving?
I've just started learning the core web dev fundamentals - HTML, CSS, JAVASCRIPT. I am also taking a Ruby course on Udemy, and as mentioned, starting The Firehose Project in September. Two ideas so far: a. idea from my job (jail) b. ESL idea I always had even before starting the career as a jail guard.
Things change so fast, so I will see what happens when one of these ideas makes contact with customers.
