Part of a broader effort - I committed to learning to code about 3 years ago. At that point in time, I didn't really know why I was doing it... really out of curiosity. I kept going because it was addicting, and really an antithesis to my day job at the time (investment banking) - which I felt was corporate / bureaucratic and unintellectual.
That said, eventually, I want to start a startup. I'm building out small side projects now. I'm generally comfy with web + mobile dev, and I wanted to upskill in a "newer" technology that was more "mathy".
