The photo illustrates my personal transition from bitrix to drupal, primarily due to the change in the profile of developed sites.
Bitrix does an excellent job with streaming website creation in small and medium-sized studios (in large companies, someone uses it for small projects). Since I am moving from streaming development to content-oriented portals, after a long search I stopped at Drupal.
At some point, I thought that Bitrix is a platform on which I will build my own website development studio. At the same time he led his (very modest) projects and time showed that his projects were much more profitable. ')
The book is good. Of course for newbies.
In order to better understand my qualifications, I will bring experience with different CMS and frameworks in chronological order from 2007 to the present:
Wordpress - 2 sites (one with unique functionality)
