I was recently privileged enough to be asked to make an appearance on Django Chat, a popular podcast that consists of long-form interviews with members of the Django community.
We talked about the history of DabApps and our use of Django and Python, as well as Django performance and code organisation and various open-source packages that we maintain and use in our client projects.
