How to make a contact manager with the ability to edit from the admin panel?

Question

CMS

Greetings, how can I implement a company contact manager? Contacts should be grouped by departments of the company, each department is divided into management and employees, each contact displays a photo, position, etc. There was an idea to implement it on Bootstrap and put it on Wordpress, but it’s not clear how to make it so that contacts are displayed through wordpress and it can be displayed through the admin panel. Almost no info on google.
Are there any plugins for Wordpress or cms that are more or less suitable for such tasks? Thank you.

Answer 1

There was an idea to implement on Bootstrap

With the same success the idea "to realize in pictures" could be born.
A little more than dofiga .

Answer 2

Hand write, right?
