 # About
 
-Personal site. ORNL is my employer; nothing here is an official ORNL product or statement.
+I'm Joshua N. Grant, a geospatial systems architect at Oak Ridge National Laboratory, where I work on spatial data infrastructure, geospatial data warehouses, raster processing, and streaming systems. I came into software through plant-science research and data analysis, then worked in data engineering at ORNL and Bold Penguin before returning to ORNL in my current role. Outside work I build data tools, generative graphics, music systems, and small games — including PARQONAUT, NUMBRANE, and the other projects on [Projects](projects/index.md). This is my personal site and does not represent ORNL.
