I did almost this exact same thing back in 2015~ ish when I was in high school over Christmas break. I reverse engineered the anime streaming site Crunchyroll's API via their Android and PS3 app using some HTTP proxy application and trial + error. I ended having a proper HLS-based streaming player and Android TV app back when their Android app was still Flash based. It was lots of fun!
Maybe! I considered pursuing a job there at the time, but I opted to get a degree instead. Being located in the Midwest would've made it rather challenging anyways.
