Michael Pereira

Data journalist
and developer

Using tools to tell stories.

I analyze and extract key insights from data to create compelling graphics, meaningful interactives, and engaging stories. Check out some of my work. Sometimes I build bots that gather information and others that can chat. I write code using Javascript, Python and R. I tinker and build with Arduino and Raspberry Pi. Occasionally I teach or talk about data and visual journalism. I also contribute to a few open source projects.
