I'm Jonathan Schemoul, a consultant in the information system universe (data handling, web applications, erp softwares integration...) at JMSI (www.jmsinfor.com).
I came to the python world working on web frameworks, first in php then in python. When I had to work on data crunching and transformation for clients, where millions of data objects was my daily meal, I started to look at ways to handle all this data fast and without eating all the memory... Python was the language for this work, and PyF became the tool.
