Help needed: Money Making Technique

Hey y'all. I am a newbie in this online world. Been doing academic writing for a while but its not lucrative and has seasons. I need a new money making technique with 0$ right now.

I need ideas I can be making money with as I finish my full stack development course so I can eat. Will really appreciate.
