Jessica Kerr (@jessitron on twitter) is fascinated by how software doesn’t get easier as she gets better at it: it gets harder, and also more valuable. Jessitron has developed software in Java, C, TypeScript, Clojure, Scala, and Ruby. She keynoted software conferences in Europe, the US, and Australia. She ran workshops on Systems Thinking (with Kent Beck) and Domain Driven Design (with Eric Evans). Now she works at Honeycomb, making complexity navigable with observability.
