What is the minimum set of knowledge you need to have to successfully work on upwork?

Question

Upwork

I look at the requirements for developers on upwork. Here is one of the requirements https://www.upwork.com/job/Native-iOS-and-Android-...
Ios + Android + Laravel + Little things As I imagine that Ios that Android that Laravel - the whole universes. They say you need to focus on one thing, it is impossible to be a pro in everything. But there are plenty of jobs like this. I am currently learning and using Laravel. As for Android and Ios, I don't know anything. So what is the minimum skill set to work on Upwork? They say the ability to sell yourself, but if you don't have the necessary skills...

Answer 1

ios + android + laravel - this is complete nonsense.
These are three different developers.
You have to be good at at least one thing.
Again, each of these technologies implies a whole bunch of related technologies that you need to know.
