You Should Know About Me

Key Strengths

Viral marketing • A/B testing • Analytics • Mysql • data mining

Key Accomplishments

I (co-)founded Circle of Moms and Team Rankings. In both cases, I built the initial product.

I led the analytics team at LinkedIn early on, and built much of PayPal's initial fraud detection technology.

How I like to work with people As a Cofounder

I am good with data, and understand how online ecosystems work together.

I am good enough as a developer to build a decent product and scale things out, but I'm certainly not a world-class developer.

I enjoy product marketing as a means of making something work from a user/product perspective.

I'm a naturally intuitive person, but extremely responsive to data.

I have a good understanding of what it takes to make a startup successful.
