✋ Hi, I’m Den.
I’m a frontend architect, author, and developer.
I build web systems that scale: fast, accessible, and thoughtfully crafted.
With over 25 years of experience, I’ve led frontend architecture for design-led global brands, written books on JavaScript development (actual paper ones), run a popular blog, and created tools that help teams debug issues and ship better experiences.
Trusted by teams at Canva, Nike, Volvo Cars, AKQA, and more.
