I'm a county GIS Manager for a county in Illinois near Chicago. I've been working in the field for 10 years, all of it in local government, after making a career change. Although I primarily use ESRI products, I have become extremely interested in open source GIS in recent years, particularly QGIS, PostGIS, and GeoServer. While we have slowly introduced some open source tools into our workflows, the potential to do even more with open source tools in conjunction with traditional proprietary tools excites me.
