I am particularly interested in location analytics, blending Business Intelligence with spatial analysis. Examples include retail/real estate site selection, trade area analysis, customer research, and marketing through demographic analysis.

I use Python for process and workflow automation, database reporting & manipulation, and developing new spatial tools.

I've been a GIS professional for 15+ years, most of which using ESRI tools (since Arc/Info 7.x). More recently I find myself using more open-source tools (QGIS, PostGIS, GDAL/OGR, web-based tools) and ultimately choosing "the right tool for the job" rather than being tied to a single vendor or toolset.

I'm not sure about integration with cartodb, but I recently saw this post about making 3D maps from QGIS using the three.js library. You may want to take a look at that.

comment Count number of attributes for unique field values
The only possible issue with using the Frequency tool instead of the Summary Statistics tool is that Frequency is (ridiculously) only available with an ArcInfo/Advanced license.
