Hi, I'm Aaron Lasseigne.

I'm a freelance software developer, an open source maintainer, a Ruby group organizer, and author.


For more than a decade I've lead projects, maintained legacy code, and managed teams. Most of my professional work has focused around building Ruby on Rails applications. I've also worked on dynamic JavaScript front-ends using jQuery, Backbone, and most recently with React.

Outside of my professional career I've explored a variety of languages with two of my favorites being Clojure and Elixir. I enjoy working on open source and tinkering on personal projects.


I created ActiveInteraction with Taylor Fausak to provide Rails with service objects that fit seemlessly into the existing ecosystem. With 900+ stars on GitHub it's been a great success.

Tables of Stuff

Built using Middleman and a healthy dose of React, Tables of Stuff provides easy to search tables for a variety of character encodings. Check out the ASCII table for an example.


I've been a regular attendee of the Dallas Ruby Brigade for several years. I've presented a variety of talks to the group and most recently have taken over as a co-organizer. I've also volunteered for Rails Girls, presented to high school students on software development as a career, and sat on the computer science advisory committee for Brookhaven College.


Blogging has helped me grow as a developer and provided another avenue for me to help others learn. I started blogging in 2012. In that time I've been in featured in Ruby Weekly 13 times including the top spot for an article covering new methods in Ruby 2.2 which was re-tweeted by Matz (the creator of Ruby). I've had articles appear on the Ruby5 podcast, Ruby Inside, and a variety of other sites. On occasion you'll find my writings on Sitepoint.

  1. Keep Ruby Weird 2016

    Keep Ruby Weird could easily be called “Remember Ruby’s Fun”. It’s a one day, one track conference in Austin that pays homage to the days of why’s (poignant) Guide to Ruby. Born in Austin, whose slogan is “Keep Austin Weird”, the city and conference didn’t disappoint. After parking my car in the hotel garage, I stepped into the elevator, and met with this disaster:

    Two columns of elevator buttons reading from left to right and top to bottom -1, ⋆1, -3, -2, 0, -1.

    On my way home the elevator stopped in the lobby with 3 men in it. I waited for someone to exit but they stood fast looking confused. I pressed “-2” to go to my floor in the garage. When the doors opened one tried to step off but the others stopped him. He exclaimed, “Where are we supposed to get off?” I can’t confirm it but in my heart I believe they’re still on that elevator.
