I've been a developer for well over a decade now. I've worked for ecommerce sites, design firms, and did freelance development for a long time. I have experience setting up servers, using third-party services, building bots for various systems, and more. I also built a pretty popular collection of mixins for Django's class-based views. Some of them even got merged into Django itself.
I'm also a frequent conference presenter and sometimes do programming live streams.
