I'm the Senior Engineering Manager of Performance at Etsy and the author of Designing for Performance. Follow me on Twitter, read my blog.

I champion performance as a part of the overall user experience, striking a balance between aesthetics and speed, and building performance into company culture. I also believe it's important to celebrate career achievements with donuts.

Building a Device Lab, a tutorial with Destiny Montague

At Etsy, we’ve built a device lab with 30+ devices and iterated upon the lab as we learned more about how developers and designers use it. We approached building it like a product for internal users, and are eager to help others build out their labs so we can learn from each other. We have presented this tutorial at Velocity Santa Clara and Velocity NY.
