If I were you I'd try to combine programming with what you're already doing (finance/business). Like learn Python and how to extract data or something, thats easily added to your current knowledge. Then later you can learn some basic web development and build nice dashboards. There are some jobs out there for finance people who can program - That's what I'd go for if I were you. It's a shame to let all your experience go to waste by learning something like systems programming or android development, don't do that I think. The "How" is really easy, simply google/udemy/coursera/etc etc. But spend some time on figuring out What first.
