Data thinking, product building.
I build tools that solve problems — web extensions, written content, apps, and whatever else comes my way.
Hi there, I'm Dmitri Spiropoulos. VizBuddy, PlotStack, and everything else here originally came from the same place: something I wanted to exist that didn't, so I built it. Take a look around, and reach out if you have any questions or want to collaborate.
