Thanks Trufi!

As this is more of an MVP for now, I mainly rely on APIs such as Google Geocoding API, Mapbox, etc in the backend, but this is certainly limited. If there was a dedicated user base who found value in this, I'd look to increase granularity/accuracy and reduce costs by working with raw spatial data and doing GIS/network analysis type stuff in-house instead.

Although, I do use OSM on the site as a map view source!
