I built a complete infrastructure of a CMS/WebEditor I've written in Python/Django, hosted on VPS.
I think I can write you some texts about plateform infrastructure for Python, about a good usage of django, maybe websockets implementation with django, and about nginx and uwsgi couple.
I can't writte about Flask, gunicron, gevent, tornado, twisted, as I only know enough about them .
I'm writting right now some short articles in french for my own business.
I can make regular translations and split into much smaller articles if needeed.
Depends on article lenght, I should be paid approximatively 1int/caracter, 7 inr/word, 150inr/page.
Cheers
