Any good programming side hustles?

I have a fine job but I’m always looking to get into new areas and learn. It’s not so much about the money I would make on the side but I feel a sense of accomplishment that I could produce software that someone buys.

Web development is an obvious but I’m curios what this community does on the side.

my friend makes roblox games on the side. It's a kids game platform that generates more monthly users than minecraft (100m). He made over 100k usd from it within a year. The platform uses LUA as their programming language.
