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 Vineyard Vines, The Boston Globe, LEGO, Global News, and consulting on performance and accessibility. In 2020, I created the Lightning-Fast Web Performance online course, and I'm the author of Responsible Responsive Design and co-author of Designing with Progressive Enhancement. I’m an active partipant in the web design and open source community, frequently presenting at conferences like An Event Apart, Smashing Conf, creating and maintaining open source projects, and regularly blogging about accessible, sustainable, and performant practices for cross-device development.

Thanks for stopping by!

New! Online Course.
