Hello.
I am a GIS expert.
Since 7 years before I have been working GIS applications.
I graduated GIS special education course and I have rich experiences for development GIS applications using GoogleMaps,OSM, Mapbox, ArcGIS SDK,GeoServer, PostGIS and PostgreSQL etc.
And I have Web technology such as C#,Java,PHP.
I checked your requirement and I am very interesting in your project.
The MonogoDB 3.2 has geometry storage type for GIS application so you can implement it for your requirement.
You didn't mention more details, but I think that I have ability to realize it.
I am ready to anything what you want.
If you should hire me, I can help you faithfully.
I would like to heard from you.
thank you.
