In my youth, to make some bucks i also worked as freelence writer, webmaster an so on… offering online services. Fiverr was one platform i used to take jobs.
The gig economy is charming, leave you space, time to make what you like, and you learn a lot especially because you meet new people around the world.
i used to work with people from all countries around the world (americans, frenchs, polishes, germans, spanish and so on). Regardless the timezones, I worked a lot and learned as much.
