I run Stochastic Solutions, a consulting and software firm specializing in analytical modelling and optimization, particularly in direct marketing and related areas. I developed uplift modelling. I'm also a Visiting Professor of Maths & Stats at Edinburgh. I advise Fluidinfo, a company building an shared, writable datastore based on tags with values.
I write a lot of python code these days.
I'm signing up more to find Django people than as a django person, though I have used it.
