Hello dear people

I would like to read suggestions from you as to which programming language is actually best suited to get a real estate portal from the ground.
The portal also includes admin dashboards, such as the one used by the admin of the page to manage the entire page, block users, images (spam), individual photos, and much more functions like digital offers.
Furthermore, search profiles for real estate are to be created. In the backend, the system searches for properties based on the search profiles and sends them to the user via email.
A lot of work is done with text and images on the page. Likewise with XML files.

Or does it really matter in principle which language you use for which project, as long as the programmer is good at coding (frontend and backend)?
