Jessica Kerr

Jessica Kerr, summer 2020

In real life, I’m a mother to two teenagers and their cats. We live in a rectangular prism on a strangely shaped street near St. Louis, MO.

Consultant, developer, symmathecist

Jessica Kerr moves between software development, speaking, and consulting. She works across languages and communities, spreading cheerful deep thoughts. Code, tools, and people are not separable; all form the team that operates useful software.

She speaks about automation, git, acceleration, functional programming, growth, concurrency, products, property tests, and progress. Her talks use languages including Java, Ruby, Elm, Clojure, Scala, TypeScript. She’s flown to Australia, Canada, nine countries in Europe, and all across the US; she misses all this very much (in 2021).

She has contributed articles to InfoQ, 97 Things a Java Programmer Should Know, and other sites which she will add to this page when she remembers their names.

As a host, she podcasts on Greater than Code and Arrested DevOps. She also appears on many other podcasts.

Don’t miss her best keynote about cameratas and symmathesy.
