Scott Jehl presenting on stage

Hi, I’m Scott. I work alongside the bright folks at Filament Group building websites and applications for clients such as the Boston Globe, LEGO, Global News, eBay, and more. In 2020, I produced the online course Lightning-Fast Web Performance, and in 2014 I wrote Responsible Responsive Design. Also, back in 2010 I cowrote Designing with Progressive Enhancement. I regularly speak at conferences like An Event Apart, Smashing Conf, and Performance.Now(). I’m an active participant in the open-source community, maintaining projects that focus on accessible, sustainable, and performant practices for cross-device development.

Thanks for stopping by!
