Do I need to separate my personal account from the site?

Question

CRM

Hello. We've got a big real estate system in development, although it's not that big of a deal. At the moment, a personal account based on CRM has been implemented, there are graphics, feedback, etc. in general, a complete mincemeat.
Now the task is to create the main site "shell". Regular company website with content.
Question: is it worth separating the personal account system from the main site? The programmer who made the personal account says that this is not correct and you don’t need to do this, they say you need to continue to make the external part on codeigniter. Most likely, the programmer does not want to lose money and wants to make money on the development of the external part of the site.
Despite his knowledge and experience, this programmer is difficult to work with, behaves like a terrorist, constantly blackmails and raises prices, thinks up problems, etc. basically a complete sociopath. We want to separate part of the project from it, let him deal with his personal account.
I think that there is nothing wrong with the fact that the main site will be separated from the CRM of the personal account. How would you do it or what is the best way?

Answer 1

It all depends on how much the public site and personal account overlap in terms of functionality.
Find a programmer you feel comfortable working with and let him decide what is best for you.

Answer 2

Regular company website with content. Question: is it worth separating the personal account system from the main site?

How are they generally connected, personal account and the main site?
It is possible to separate (it is worth it if such difficulties with the programmer), nothing terrible will happen.
PS Why work with such a programmer?

Answer 3

Yes, share, it's okay. So split the load between the website and the CRM. Do the main thing correctly.
(I hope there is just a static site with no connection to your CRM, otherwise there is an admin panel with content editing, widgets from CRM, etc., then you will run into a separate project for the main site, with your admin panel, user, integration with CRM - and this is an additional expenses)
