I've worked for both of the major players in the python data science world (Enthought and Continuum) where I contributed to their open source efforts and client projects. I've been a contributor to NumPy, SciPy, Scikit-Image, and many projects in the Blaze ecosystem. You can view my github profile here https://github.com/cowlicks Other python projects I have experience with: django, flask, scikit-learn, twisted, and others.
