Update:
Depending on the opportunity, I occasionally provide high-level consulting on personalization, customer and product targeting, and discovery technologies. I specialize in extremely rapid, data-driven product development [*], building high-speed, large-scale data mining systems, and the art of balancing academic rigor and creativity with the need to just get things done.
I work best with young companies or early-stage initiatives in larger companies. I've worked both with startups, both pre- and post-funding, and the Fortune 500.
If you don't know what to build and want to figure what the right thing to build is, you should probably talk to me. If you already know exactly what you want and just need someone to write it for you, I'm probably not your guy.
[* Since rapid prototyping is a buzzword these days, I'm talking about data to concept to prototype to launch in 4 weeks.]
