Your disagreement stems from my use of the term "tasks" instead of "contracts." From my perspective, tasks can be seen as miniature contracts. For instance, if I were contracted to build a website for a school, I could divide the work into smaller tasks. I might hire someone on Fiverr to handle the frontend development, another person for the backend, and a graphics designer to manage all the visual elements. These individual assignments could be considered tasks. Tasks can be assigned to individuals who are not employed full-time, as long as both parties agree on the terms
I just want to say, in order to complete those tasks or contracts you need to have skills. Skills that you need to learn and master. If you are not good enough and unable to create a good portfolio you are not going to get those tasks done. But the list is good. If you have skills to show off then I guess these online platforms are the best place to do so.
If you want to make the big bucks, you will have to learn multiple things at once and also need to be good at it. It's hard but with practice and patience it could be done. And you are doing those jobs sitting in your home. So what better way to earn than this. Thank you OP for sharing. There are some that I didn't know about before. I might give them a try.
