Hi, my name is Speros. I’m a data visualization designer and developer with a focus on interactive pieces that utilize dynamic data sets for exploration. I create open source software and write about visualization on the web.

I'm currently working at Google on Malloy, building a nested data visualization renderer for fast and powerful ad-hoc analytics. Previously, I co-founded Knarr, a cloud-based data analytics tool with real time collaboration for rapid data exploration and decision making amongst teams. Knarr was acquired by Qlik in 2020.

You can find me on Twitter and YouTube.
