Decide on a python stack for further study?

Question

Python

What is:
-Experience in various languages: java, c#, c++, as3, js. For all - superficial (building a mind map of the language + a few examples), except for c ++.
-Bad algorithmic base.
Purpose: freelancing.
Bad algorithmics + freelancing - I see only web. Therefore, in parallel with the language, I took to study django. But I still want not site-ripping, but something serious and important (ambitions, sir). What can it be and, accordingly, what stack should be chosen for development? From bases - postgres. From the "serious and important" the first thing that comes to mind is bigdata.

Answer 1

Elasticsearch + redis, this is for databases.
Also flask and httpio/asyncio

Answer 2

I myself recently got a job for the first time in the Python office as a developer, I can say that the former attitude to the web as something simple was blown away by the wind, despite several of my own implemented projects. The company uses the following stack: django, PostgreSQL, angular. And as far as I realized, the business appreciates exactly the full stack of developers, who optimize the requests and fasten the asynchronous registration form and fix bugs and raise the server. All in all, dig deeper, the web is a good choice!
