Implement sprint backend edits in PHP

Hello.

It is required to implement a sprint of edits to the backend of the project on Bitrix. 12 tasks for the standard 2 weeks. Bitrix project, you need a PHP developer. Not an expert on Bitrix, but a PHP programmer since the project is complex and you need to work with the code, and not ask for access to the PA and try to install plugins.

There is a ready-made DevOps with a demo server. The sprint is pre-evaluated. The project has documentation. Payment is hourly.
