I am a Django core developer. I work at Divio, and live in Cardiff, where I help run things like PyDiff, PyCon Namibia and PyCon UK.
I've been, with various degrees of success, a high-school teacher, a company director, a philosophy lecturer and some other things I don't care to mention, but what really worked was becoming a programmer a few years ago.
I'm heavily involved in the international Python/Django open-source software communities and have a special interest in open-source software development in Africa
