What's my next step?

I just found this site and I think it's amazing :) Lots of great energy and people here.

So a bit about me - I am semi-retired, just need to do some freelance writing everyday (part time). I want to transition into software products. I did take a bootcamp 5 years ago and did complete freecodecamp.

I just don't know where to start. Like I don't even know if I should try building mobile apps, wordpress plugins or SaaS.
