This question is just to have an idea of the effort that has gone into building CiviCRM. How much time will it take to build CiviCRM from scratch by a single person? including testing and fixing the bugs.

All of it? Probably 10 years.

(that's a serious answer - I know, as a member of the core team, I built a lot of it myself)


Building the entire thing? My guess is at this point it's tens of thousands of hours.


Considering you're attempting to create an ever-evolving target, I'd say that you'd never be able to do it.
