Episode 076 - Making Storefronts Faster One Device at a Time with Georgi Petrov of Uxify

<p>Georgi Petrov, CEO and co-founder of Uxify, joins Karl and Taylor to talk about the half of web performance nobody optimizes for: the shopper's device. After building SMS Bump (acquired by Yotpo), ConsentMo, and NitroPack (acquired by WP Engine), Georgi is now tackling device-specific friction, the laggy buttons, layout shifts, and interaction delays that vary wildly from one phone to the next. We get into how Uxify profiles a visitor's capability without touching your code, the specialized agents that fix problems on the fly, the ClickHouse-powered data layer behind it all, and how to think about performance heading into BFCM. Plus the Dev Changelog and Picks of the Week.</p><p><b>Sponsor</b><br>The Support Heroes: <a href="https://www.thesupportheroes.com/?utm_source=liquid_weekly&utm_medium=podcast&utm_campaign=sponsorships">https://www.thesupportheroes.com/</a></p><p><b>Subscribe to Liquid Weekly</b><br>Don't miss out on expert insights and tips.
