To build innovative products in an exciting, fast-paced, socially-conscious organization.


I am a technologist who works with engineers, product managers and executives to define technology and product strategies, and build systems realizing them in both large and small organizations.

I have built some of the world's leading Web sites and systems supporting them, developed by teams ranging from 10 to 100s of engineers, and used by hundreds of millions of users.
I have participated in the definition of aspects of the technical and product strategies of companies that are leaders in their field.
I have written mission-critical code and still have hands-on involvement involvement with the engineering teams I work with.
I have written Web standards and a book, and have given technical presentations to large audiences around the world.
