I am a software engineer at DroneDeploy where I specialize in implementing back-end systems for geospatial data processing and analysis. I came to DroneDeploy from Carnegie Mellon, where I received a Master of Science in Computer Science degree in December 2018. Before grad school, I spent a combined six years working as a geographic information system (GIS) analyst and developer at renewables startup Origin Solar Energy and environmental consultancy The Cadmus Group.
