Jessica: @jessitron

Almost 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 and

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.





Sam: @geeksam

samSam Livingston-Gray has been a dad since 2008, a Rubyist since 2006, a Portlander since 2001, a programmer since at least 1998, a juggler since 1988, and a human since 1974. He’s keenly interested in writing software that makes other humans’ lives easier, in making technical topics easier to understand, and in helping increase the number and variety of humans* in technical spaces.

* And, of course, other sentient species or constructs just as soon as we find any.**

** Sam reads a lot of science fiction.




Jamey: @jameybash

Jameson Hampton is an artist who turned into a programmer after one too many animation classes that were computer science classes in disguise. They love writing code because they love solving puzzles. They’re a professional plant-liker (and software engineer for Agrilyst. They also speak at conferences, particularly about transgender advocacy and engineering ethics. For me, check out their blog at!

Jamey is passionate about both making zines and reading zines. They are the resident zine librarian at Sugar City Arts Collaborative.

Jamey’s greatest wish is that they were immortal so they’d have time to visit every coffee shop in the world. They spend their free time thinking about Star Wars, being a world ranked scavenger hunter, and going out into the woods to set sculptures on fire.


Astrid: @ianthro

Astrid is a Ruby Nuby (programming in Ruby just 2 years), anthropologist and writer. She slowly worked her way over to software development by managing and the building databases and working as a data analyst. Then she went all in and attended The Iron Yard Academy in Houston. Afterwards she worked at HP as a QA Engineer and DevOps Engineer. Now she is the Director for Tech for Justice and a freelance software developer.

Astrid is all about learning and growing as a developer and tech diversity advocate. She encourages girls to code through coaching for organizations like Rails Girls and is currently teaching herself Python so that she can also become a pyLady. Astrid is still an active social scientist and helps moderate a slack group called AnthroHangout. She spends her spare time binge watching Netflix and spending time with her husband and 3 dogs.




Janelle: @janellekz

Janelle is a NFJS tour speaker, and author of the book, Idea Flow, a technique for visualizing the friction in flow between a developer and the software, like an EKG that monitors your pain and creates a feedback loop that helps you improve.

After researching Idea Flow for years, Janelle turned into a hobbyist cognitive scientist, obsessed with the challenge of building a brain in code. After a 17-year career as a developer, consultant, and CTO specialized in data-intensive analytics, she is now a full-time entrepreneur on a crazy mission: to bring free mastery-level education to every human in the world by conquering generalized AI.




Rein Henrichs: @ReinH

Rein is a strange sort of software developer who spends more time thinking about systems made with people than systems made with computers. He believes that most technical problems are really people problems, and that people problems can be solved by listening, caring, and empowering others. Talking about himself in the third person makes him uncomfortable, but he is working on it. He also wrote a database in Haskell once, so he has that going for him, which is nice.







Christina Morillo: @divinetechygirl

C:\hristina is a New York City-based information security and technology professional with a background in enterprise-level security and identity management. By day she works at Microsoft as a Senior Program Manager on the Cloud & Engineering Security team.

In addition to her professional work, Christina also co-founded a community for women of color in tech, which is best known for their open source collection of stock photos. She enjoys spending time with her family and loved ones, problem-solving, boxing and most recently, yoga. She lives in New York City with her husband and children.




John K. Sawers: @johnksawers

Amongst John’s weaponry are public speaking, doing the rails thing, and talking about feelings in public. His technology talks aren’t about technology and sometimes he has time to meditate. He remembers the sound of dialup.

Soon, John will no longer write much code, having intentionally (yes, intentionally) moved into management. He seems to think that making people better is more satisfying than making computers better. With that in mind he’s also spent a lot of time mentoring bootcamp developers and supervising workshops focused on deep emotional work.

He spends days at Privia Health, nights as co-founder and CTO of Data Simply and all the rest of it at and

He’s a consulting pair-programmer, the author of several popular Ruby programming books, and a recipient of the Ruby Hero award for service to the Ruby community. Since 2011 he has been teaching developers how to work more effectively (and have fun doing) it at

He spends his theoretical spare time hanging out with his kids, hiking the Smoky Mountains, and dancing to oontz-oontz music.
