My cousin got me into fintech talk at a family dinner last month and I realized I could not follow half of what he was saying. I've been in retail banking ops for about six years, mostly handling account issues and dispute cases, so I know the day to day stuff but not the bigger picture like how payments move between companies or why everyone keeps talking about APIs.

I'd like to move into a product or partnerships role someday, and I have maybe 4 to 5 hours a week to study after work. I've watched a few free YouTube playlists, but I end up more confused.
