Who I am

Shopify developer specialized in Liquid, custom JS, and page builder migrations to native code.

I instrument GA4, set up GTM, run A/B tests, and read Clarity heatmaps, then I build what the data says to build. Lately I've been adding AI workflows and MCP integrations to move faster without adding headcount.

Case Studies

Selected work

2026Beach Riot

Custom Mix & Match section + A/B test

The client needed a way to let users build custom bikini sets directly on the PDP. Built a Mix & Match section in native Liquid + JS no app, no builder. Ran an A/B test tracked in GA4: ATC rate went from 15.3% to 16.5%.

2025The Wellness Company

Full Shogun → native Liquid migration

Led a full Shogun-to-Liquid migration across 1 homepage, 10 PLPs, and 20+ PDPs. Coordinated developers, a designer, and an account manager delivered on time with zero incidents.

2026Internal Power Digital

AI Dev System

Our dev team was losing hours every week rebuilding the same Shopify patterns store after store. Together, we built CRO-Builder an AI system powered by Claude + MCPs that captures repetitive tasks and generates production-ready Shopify code on demand, with or without design. Result: 40% to 90% faster execution, zero bottlenecks, adopted across the entire team.

2026La Obra de Arte Soy Yo

Ongoing CRO advisory + Shopify development

Users weren't engaging with the homepage they landed and left without exploring. We diagnosed the drop-off using Clarity heatmaps and GA4, restructured the homepage flow to guide users deeper into the catalog, then improved the PDP experience to reduce friction at the product level. Ongoing engagement I identify the opportunities and build the solutions.
