Rollup Summary of child records on the parent

Is there a way to roll up the count of child records on a parent record?
Like a batch job that calculates this on a daily basis and updates the parent record with the count.

Parent Thing: User
Child Thing: Likes

Field on the User called “Total Likes”

**Incrementing and decrementing the value on the user is not an option, as we need the ability to import data frequently
