I build clarity into complicated work.
Most of my work starts with something messy: an idea that is difficult to define, a manual process held together by memory, or a workflow that asks too much of the people using it. I like getting close to the problem, asking the questions that change the direction, and turning what I learn into a product people can actually use.
