I'm an Engineering Director at Etsy and the author of Designing for Performance and Building a device lab. Follow me on Twitter, read my blog.

I champion performance as a part of the overall user experience, help people get comfortable giving presentations, and believe it's important to celebrate career achievements with donuts.

Designing for Performance

©2014, published by O'Reilly

Designing for PerformanceDesigning for Performance is a practical introduction to performance from a designer and front-end developer perspective. It covers performance as part of the overall user experience, how to measure the speed of your site, how to weigh aesthetics versus speed as you build or iterate on designs, and how to change the culture of your organization to care about performance.

The book is available to read for free at, but I'm also donating all of the proceeds from book purchases to various charities focused on supporting underrepresented people in tech, including Girl Develop It, Women Who Code, Black Girls Code, #YesWeCode, Latinas in STEM, Hack the Hood, and DonorsChoose projects like Growing "Girls with Gadgets"! and Girls Can Code, Too!.

Helping VIPs Care About Performance (24 Ways)

“What metric(s) do your VIPs care about?” This question is often met with blank stares and raised eyebrows. But it’s also our biggest clue to what we need to do to help empower others to care about performance and work on it. Every organization and executive is different. This means that three major things vary: the primary metrics VIPs care about; the language they use about measuring success; and how change is enacted. By clueing in to these nuances within your organization, you can get a huge leg up on crafting a successful pitch about performance work.

Performance: Showing Versus Telling (A List Apart)

Take your message to the next level. Help those around you feel the impact that performance has on your overall user experience. Showing is so much more compelling than telling; showcasing the real user experience is much more powerful than staring at numbers or bar charts. So how can we show performance? Use videos of your site loading, and wall monitors! This article shows you how.
