How a 21 Year Old Builds Shopify Apps With AI Agents

Taylor is in India for Shop Quest, so Karl flies solo with Charles Swayne, owner and app developer at JadePuma Apps and the person behind Datify. Charles is 21, learned Python in sixth grade, and now runs a multi-agent development workflow that researches, plans, audits the plan, executes, and tests itself before he ever looks at the code. We get into what that workflow actually looks like, which models he reaches for at each step and why, how he runs his own evals, and whether any of us should still be reading the PR. Plus Datify, structuring product data for agentic commerce, and what it was like when Mantle shut down. ▬▬▬▬▬▬▬▬▬▬ SPONSOR Promo Party Pro is a free gift with purchase app Karl helped build with the team at Ethercycle.

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

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.

The Hidden Complexity of Going Global

Episode 069 – The Hidden Complexity of Going Global Karl 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 Weekly Don't miss out on expert insights and tips—subscribe to Liquid Weekly for more content like this: https://liquidweekly.com/--- Find Kwadwo Adu Online Website - https://adu.dkLocaleFlow App - https://localeflowapp.com--- Timestamps 00:00 – Show intro; localization blind spots for US devs01:10 – Introducing Kojo Adu and LocaleFlow01:47 – Kojo's background: Copenhagen, Barcelona, e-commerce since 201003:22 – Taylor's Barcelona experience; why "everyone speaks English" isn't true05:20 – How Kojo got into Shopify development back in 201006:26 – Origin story: partner saw the problem daily, LocaleFlow was born09:38 – Market validation: start with someone who'll pay from day one13:05 – "Just use Google Translate" — why it breaks on real Shopify stores16:27 – How LocaleFlow handles the full translation stack19:16 – Multi-LLM pipeline, brand name blacklisting, tone-of-voice prompts22:42 – "Nice pricing" and currency conversion complexity across markets27:25 – Localizing metafields and metaobjects: the special sauce29:11 – Tech stack curiosity: PHP, Rails, and building with AI33:15 – First impressions of Fable, the new AI design tool35:27 – AI workflow philosophy: set guardrails, then let go37:24 – Agentic loops vs. human-in-the-loop in practice41:26 – Shopify Dev Changelog45:24 – Picks of the Week--- Dev Changelog - Cart lines now identifiable by view key - https://shopify.dev/changelog/cart-line-mutations-accept-view-key – The Cart Lines Update and Remove mutations now accept a view key to identify cart lines instead of relying solely on Shopify's generated line ID, giving developers more stable, predictable cart operations. - App quality checks moved to partner dashboard - https://shopify.dev/changelog/app-quality-checks-now-managed-in-partner-dashboard – App quality checks and action items are now managed directly under Distribution in the partner dashboard, replacing the previous email thread experience. - Local currency support for gift cards in GraphQL Admin API - https://shopify.dev/changelog/gift-card-local-currency-support - Gift cards can now be issued and managed in local market currencies via the GraphQL Admin API, a meaningful step for merchants running Shopify Markets internationally. - Headless checkout SSO parameter change - https://shopify.dev/changelog/headless-checkout-sso-is-now-documented-with-ssosilent – The query parameter for headless checkout single sign-on has changed from `logged_in=true` to `sso=silent`; update any headless implementations that reference this parameter.--- Picks of the Week Karl: CoDiff - https://github.com/nkzw-tech/codiff – A GitHub diff viewer Karl wants to try for reviewing the large, messy diffs that come out of agentic coding workflows.Kojo: Orca - https://www.onorca.dev/ – An agentic IDE that feels like a blend of Claude and Conductor; Kojo's current daily driver, with a particularly good mobile app.Taylor: Bullet Point Mounting Solutions - https://www.bulletpointmountingsolutions.com/ – A MagSafe vehicle phone mount Taylor installed in his truck; available on Shopify and highly recommended for anyone fumbling with their phone while driving.
