Answer 1

The question is really very popular :) But, I think, people will throw a pile of their proposals, and you will have to choose something for yourself. As I see it, your knowledge is quite extensive, but also familiar.
Try playing something exclusive that isn't particularly busy but is required. For my part, I will advise this direction (there are interviews with Germans who do amazing things).

Answer 2

Of course, you will excuse me, but dozens of exactly the same questions that are asked every few days - they are not for you, right? Do you have a special question and has the situation on the market changed in 2 days since the last same question?

Answer 3

Our age is the age of specialization, so choose an area that has a demand for technology, delve into it and take orders first at any price. You will understand further.
ps you can send me skills to the mail later, I will unsubscribe if there is an order.

Answer 4

You can start from scratch.
The tasks are very different.
