Building teams that put data to work

I've led work in product, engineering, design, and communications. Knowing how it all fits together gives me the confidence to sweat the details without losing sight of the mission.

From public to private. From an audience of one to audiences of millions. From elections to disease surveillance to research infrastructure. I make data useful for people and machines.

Managers are supposed to slow down, but I'm writing more code than ever. Earlier in my career I focused on building robust open source tools, like csvkit. Today I use teams of agents to build more, and better, than I ever could alone.
