Mary Sprague
Building mapping tools, climate resources and nature apps that turn complex environmental data into something people can use.
I’m a software engineer in Berlin working where environmental data meets product. I build the full path from raw data to the interface people use: backends and spatial databases on one side, clear, fast map experiences on the other.
Recent work includes a catalog of urban climate-adaptation tools, an urban wildlife identification app, and a browser instrument that turns city climate data into music.
