Possible to set geofence around specific points saved in database by an application?

Question

I am working on an application which I can use to create custom geo-fence.

For that, I want to get the coordinate of the location (latitude, longitude) and save that in the backend database using the app.

Now for each point saved, I want to create a geo-fence around each of those points, say with 10-KM radius.

The entry and exit action for all of them will be same.

How to accomplish this ? Can be be done ?
