Jim grew up in the San Francisco Bay Area. He graduated from Berkeley with a BA in physics and from Princeton University with a PhD in the same field. After defending his PhD, he realized that he wanted to move back to San Francisco. That was during the time when you would find job ads in newspapers. He saw several open positions for software engineers and Easter Bunnies – the latter because it was close to Easter. He thought that the Easter Bunny thing was going to be seasonal, so he went with software. The decision landed him at Scopus Technology, where he worked on the first generation of call center applications. That was in 1994, and Jim spent the next 10 years doing enterprise software at Scopus and other companies. Jim has been an engineering leader at Quantcast since its beginning in 2006.
