I was the founding designer at Balsamiq, creator of the Wireframing tool, and co-author of the book Wireframing for Everyone.

I worked in various roles prior as designer, information architect, and front end developer at companies including Google, Sling Media, Sapient, Bell Labs, and the Metropolitan Museum of Art. My CV is on LinkedIn. I was a co-founder of the Information Architecture Institute and published several blogs since 1998 including studio id, iaslash, urlgreyhot and the former blog and UI showcase of this site.

The tool I've shared that's been most used is a Wireframe Stencil made for OmniGraffle — it ships with the product. I also hear from people occasionally that they still use my Printable Graph Paper and DIY Sketchbooks.
