I’m Brennen. Since 2019, I’ve been a member of the Release Engineering team at
the Wikimedia Foundation. We provide the tools and services that enable
software development for the Wikimedia movement, deploy the code that runs
Wikipedia, and care for the health of Wikimedia production in various ways.
From 2007 to 2014, I worked at SparkFun Electronics, an electronics
retailer which has helped to redefine the hobby electronics market, technology
education, and open source hardware. Between 2014 and 2019, I contracted for
Adafruit Industries and did a stint as a technical writer for
DigitalOcean. At Adafruit I wrote educational materials, worked on the
in-house webdev team, and eventually landed as a Creative Engineer with a focus
on the Raspberry Pi and CircuitPython.
