additional background:
back when I had a "career," I did mostly backend web app dev, most of that on horrifying PHP codebases, a bit on Django but that was when I was already close to burnout. I was also better at front end than most engineers in similar roles, but that was like 15 years ago and front end is way different now.
web apps is what I know. but I want to get into mobile development because I'm convinced it's a good fit for my mind and its various quirks.
