Jessica Kerr is a symmathecist, in the medium of code. She believes in learning systems made of learning parts: enthusiastic people and evolving software. In twenty years of professional software development, she has worked in languages from Java to Scala and Clojure, from Ruby to Elixir and Elm, from bash to TypeScript and PowerShell. In her years as a conference keynoter and speaker, she has talked about all of these, plus the deeper work of software development. She finds inspiration in resilience engineering, systems thinking, and art. She loves helping developers automate the boring bits of our work and express more creativity in the rest. Find her learning out loud on twitter (@jessitron), live coding on twitch (jessitronica), writing at blog.jessitron.com, and raising two new unpredictable people in her home in St. Louis, MO.
