CMS modification on Symfony PHP

Need to make modifications for web application for CMS panel based:

Backend (Apache + PHP7 + MySQL):

- Symfony 3.4

- Doctrine2

Scope of changes:

- Sorting the list of users based on columns,

- Fixing data update in CMS after scraping instagram profile (data stopped updating for one particular case),

- Changed the conditions for uploading realizations by users to the platform.

I will send detailed information about the problems occurring in the CMS panel in a message to interested parties. Exact pricing expected after a thorough review of the problems in the application.

After reviewing the materials, he proposes a call to discuss the details of the operation of the application.
