jessicaAlmost twenty years ago, Jessica chose to program because it was easy and it was 9-5. Now programming is hard, she spends all her spare time on it, and she loves it immensely more.

Software is fascinating because we create complex systems incredibly quickly. This means we get to learn about complex systems, which teaches us about everything else in life. For more, see her blogs at blog.jessitron.com and tistil.tumblr.com

Jessica (better known as JessiTRON) works as a lead engineer at Atomist. Infrastructure is the best because it’s software about software. She also raises two daughters, speaks at conferences, studies piano, and stares at the waves in the milk film on her coffee.
