Bill has always enjoyed technology (25 years). And he has always enjoyed interacting with people (even longer). It was a natural to blend the two loves together.
For a long time he couldn't decide if he was a designer or an engineer. He finally gave up trying to classify himself and just decided to live in both worlds as much as possible. This passion drove him to create one of the first successful Macintosh games (GATO, 1985), build wargaming interfaces for NATO, found and lead UX Design teams (Sabre), write Ajax frameworks (OpenRico) manage user interface engineering organizations (Meebo & Netflix), publish design pattern libraries (Yahoo!), talk a lot about it (Ajax Evangelist) and even write a book about Designing Web Interfaces (O'Reilly).
Currently Bill is the Sr. Director of Web Development at PayPal.
