Precise Neighborhood Geofencing for Package Delivery

I'm looking to set up a geofence on Google Maps for a package delivery service. The geofence needs to cover a neighborhood, and it must avoid cutting through building blocks, necessitating a high level of accuracy.

The successful freelancer will be:
- Experienced with Google Maps and geofencing
- Able to work with pre-existing building data
- Detail-oriented to ensure accuracy in the delivery zones
