Liquid Weekly Podcast: Shopify Developers Talking Shopify Development

Trudy MacNabb joins Karl and Taylor for a full DotDev week preview and a Toronto survival guide. If you're heading to Shopify's DotDev in July, this is your map: what's actually happening across the week, how to get around the city, where to eat, and which partner events are worth your time, including Brightwork, the Thursday event Taylor and SWYM are throwing to fill the gap left by Tectonic. And if you can't make it this year, Karl, Taylor, and Trudy walk through it so you can follow along from home.

Episode 069 – The Hidden Complexity of Going GlobalKarl and Taylor sit down with Kwadwo (Kojo) Adu, co-founder of LocaleFlow — a bootstrapped Shopify translation app built to help merchants expand into new markets without losing brand voice, SEO, or metafield data. Kojo shares how living in Barcelona as a Dane gave him firsthand empathy for the localization problem, why browser translation falls flat for real stores, and how LocaleFlow's multi-LLM pipeline handles everything from tone-of-voice preservation to currency "nice pricing." The episode rounds out with a Shopify dev changelog covering cart line keys, gift card currency support, and partner dashboard improvements, plus picks featuring a slick diff viewer, an agentic IDE, and a MagSafe truck mount.---Subscribe to Liquid WeeklyDon't miss out on expert insights and tips—subscribe to Liquid Weekly for more content like this: https://liquidweekly.com/---Find Kwadwo Adu OnlineWebsite - https://adu.dkLocaleFlow App - https://localeflowapp.com---
