Hi, I'm Daniel Roy Greenfeld, and welcome to my blog. I write about Python, Django, and much more.


I do Python, Django, and JavaScript out of Los Angeles, California. I love to read, write, hang out with my wife, and play at Capoeira. I am a total Space and NASA Geek. I used to attend software industry events.

Fiction Works

I'm a fiction author! If you want to read about my upcoming fantasy series, check out my author blog. In the meantime, here's my first work:


Technical Works

I co-wrote an ice-cream themed book series on Django with my wife, Audrey Roy Greenfeld. The most current version is for Django 1.11, the latest Long Term Support (LTS) version of the framework. That means this book is good until April of 2020!


You can still purchase the 1.8, which is still good until April of 2018.


You can also purchase the 1.6 edition:


And the 1.5 edition
