Should I use cms or write a site for pregnant women from scratch?

Question

CMS

There are TK of the following nature:
- All the main functions of the social network (messages, photos, etc.)
- A task book for each week of pregnancy such as a checklist. Example svadba.org/wedding/timetables/7098636/events/48756914
- Services for women (determining the sex of the child, date of birth, weight tracker, etc.)
- Directory of companies that sell services and goods in the field of childhood (companies of this type VKontakte groups that users can send messages with an offer, etc.). Also, as an example, you can cite svadba.org/firms
If self-written, advise which environment to choose so that you can receive large traffic. If CMS then what.
Let me thank you in advance for your replies.

Answer 1

most likely you will have to make your own decision, because if you need a mobile application, you will need to make a rest-api, i.e. write a separate system and work with the base of the cms that you now choose

Answer 2

data life engine

Answer 3

ispolzovt CMS - hand over earlier, earlier the customer will understand what he wants
what? the one that the programmer knows
better, of course, Python than PHP, there will be no temptation to use WordPress, for example))
although in the same PHP there is, for example, modx, which is quite worth it,
but if it doesn’t matter what - look towards django-cms, for example, but, once again, it all depends on the budget for and the qualifications of the programmer
