sed·i·men·tal /ˌsedəˈmen(t)əl/ adjective - of or relating to gradual accumulation of sentiments.
I'm Mahmoud Hashemi. I write software and words in California.
This is my personal site, where I enjoy combining software and words into accessible-yet-thorough engineering guides. As of 2016, this habit has spilled over to my latest project, O'Reilly's Enterprise Software with Python.
By day, I work as a software architect and engineer at PayPal. For a number of years I've led the Python frameworks group, with a recent focus on high-performance, high-robustness application security services. You can read my PayPal writings here. You'll note the signature thoroughness/length. If you're interested in my Python background, check out this brief history.
If I have a theme song, it's SimCity 2000 music. Catch me whistling it when I think no one's around.
You can email me at email@example.com, but most people just follow me on Twitter.
