Rauno Freiberg

Rauno Freiberg is an Estonian Staff Design Engineer at Vercel who blurs the line between design and engineering with surgical precision. Known for his obsession with invisible details - the micro-interactions, animations, and tactile feedback that make software feel alive - he built cmdk (downloaded millions of times weekly), wrote the seminal 'Invisible Details of Interaction Design' essay, and created Devouring Details, an interactive design education platform. He previously shaped the Arc browser at The Browser Company. His philosophy: code is the material, and mastery of HTML, CSS, and JavaScript is the only honest path to great interfaces.
