I've been a Python developer in the background for nearly 12 years, despite often being forced to use other languages for day-to-day production code. This all changed 3 years ago, when I was able to focus full-time on Python development and training as a consultant. It was through this that I discovered Skyscanner - a company doing interesting and exciting things with Python & Django!
I also run the Python Edinburgh group, running regular meetups and occasional talks.
