Commerce Engineering

Shopify Themes Built Like Production Software.

Custom Liquid and JavaScript themes, performance budgets, and scalable checkout UX. Built with the same rigor I apply to platforms serving millions of users.

Commerce Engineering

Engineering for High-Volume Stores.

Shopify is often treated like a no-code tool. I treat it like a production platform: custom Liquid/JavaScript themes, performance budgets, and checkout flows that scale.

Custom Themes, Not Template Hacks

I build Shopify themes from scratch in Liquid and JavaScript. Clean architecture, no theme-bloat, and full control over performance and UX.

Performance as a Feature

LCP, CLS, and runtime profiling aren't afterthoughts. I apply the same optimization discipline that cut a client platform's load time from 5s to under 1s.

Systems That Outlast the Launch

Merchant-editable sections, documented code, and upgrade-friendly structure. The store keeps working long after the handoff.

Stores I've Shipped

Live Shopify builds where performance and conversion actually matter.
