Not content with overly specific job titles, I've defended good design with code, slide decks, and mocks. Screenshots don't do my work justice, but I'm always happy to talk about my process and results.
I've been at Google for the last few years, first launching new products for Maps, and now working through the challenge of serving ads ethically.
If you find yourself in need of opinions on design, technology, psychology, or philosophy, drop me a line. Some of my opinions are even well informed.
