What I Fix
The storefront problems that quietly make Shopify harder to buy from.
Most conversion leaks are not dramatic. They are slow scripts, unclear variant flows, weak product page hierarchy, broken carts, and mobile details that add friction.
Broken cart drawers
Reliable Shopify AJAX flows with clearer states, totals, errors, and upsell moments.
Confusing variant pickers
Cleaner option logic, disabled states, swatches, and mobile controls that reduce friction.
Weak add-to-cart intent
Product pages structured around trust, clarity, sticky CTAs, bundles, and buying confidence.
Too many apps slowing the theme
Replace heavy app behavior with purpose-built theme code when a leaner solution makes sense.
Generic product pages
Custom Shopify OS 2.0 sections built for merchandising, education, trust, and proof.
Weak mobile shopping UX
Thumb-friendly layouts, faster decision paths, and cleaner paths toward checkout.
Poor product discovery
Sharper collection UX, filters, product cards, badges, and browse patterns that help shoppers decide.
