Sound Refound is an online gallery of promotional flyers for concerts. I've collected these over the years, primarily in the Lawrence, Kansas, and Seattle, Washington areas.
atom-everydayrails-rspec is package of snippets to speed up and simplify writing tests in the Atom editor, as taught in my Rails testing book. I use these snippets every day to speed up writing tests!
Next projects coming soon. I'm messing around with some JAMstack stuff and fresh book idea(s) at the moment. You should probably subscribe to my newsletter and stay current.


I'm Aaron Sumner, of Astoria, Oregon, USA; by way of Lawrence, Kansas, Seattle, Washington, and Jersey County, Illinois.

I've worked on the web since 1994 when I began creating some of the very first departmental and organizational websites as an undergraduate at the University of Kansas. I'm currently a Senior Software Engineer at O'Reilly Media where I mostly write Ruby and React.

Most people who know me know me as a tech author, though; I wrote Everyday Rails Testing with RSpec and have blogged at Everyday Rails since 2010. These days I also think and talk and write a lot about embracing legacy systems, personal development and growth as a software developer, and the non-coding things it takes to be good at what we do.

I take advantage of every second I can away from a computer, too, through cooking, woodworking, running, and cat herding.

I still learn new things every day. Sometimes I share them here. Thanks for following along.
