About
I underwrite infrastructure: the models, memos, and siting analysis behind capital decisions on energy and industrial assets.
I worked on the product at Scout Cities, a tech-enabled industrial site selection firm: geospatial data management; total cost of ownership modeling; incentive discovery and economic impact analysis for state negotiations; market scoring across grid, logistics, risk, quality of life; and labor reporting and talent pipelines.
My professional background has focused on software, data engineering, city infrastructure, and operations. I was Chief Innovation Officer at AdComp Systems for three years and then for the City of Aledo, Texas.
I have also studied economics, philosophy, and neuroscience, and retain an interest in the big questions.
