Store Lab

One theme, different commerce requirements

All demo stores share Romanics, my custom Shopify theme, and are built through an AI-assisted development workflow. Each is for a different catalog, business model, and buying journey.

How these stores are built

Romanics: the shared theme
Romanics provides the reusable storefront foundation. I adapt it to requirements such as skincare routines, furniture specifications, wholesale ordering, and vehicle fitment, then use those experiments to refine the shared theme.
AI-assisted development
I use AI assistants for codebase exploration and implementation. I define what each store needs, make the architecture decisions, and remain responsible for reviewing changes and verifying storefront behavior.
