Finalization and configuration of the bulletin board/marketplace in PHP (backend/frontend) CMS Tamaranga MP 3.0

This is a voluminous project for a backend/frontend (fullstack) programmer. Experience with products from Tamaranga is very welcome.

What needs to be done:
- Development and refinement of existing modules and plugins are forms of submission of ads, stores, new advertising opportunities, registration form, contacts, etc. The new version of tamaringa is now more flexible, much can be implemented without touching the main code
- Work with the front according to the prototype on Figma and TK
- Detailed cmS configuration in the admin panel
- Internal SEO/SEM page optimization.

In general, we configure and refine the new engine "Tamaranga 3.0 MP" with filters and hooks from the point of view of functionality, according to the recommendations of the developers - a lot of work with the frontend - all depending on how possible it is to implement the requirements according to the TK, if necessary - we make alternative decisions. It is also important to keep the ability to accept CMS updates from Tamaranga.
