Advanced Customizable Shopify Themes
Conversion-first themes with deep merchandising controls.

What we needed to solve.
- Off-the-shelf themes couldn't support custom merchandising features without bloating JS bundles.
- Brand teams needed editor-friendly sections without developer involvement for every promotional change.
- Mobile page speed was non-negotiable for paid social traffic conversion rates.
How it was built.
Modular Section Library
Built a reusable library of 30+ custom Liquid sections — Shop The Look, Quick View, Bundles, advanced filtering — that brand teams can drop in via the theme editor.
CRO-First IA
Restructured PDP and collection templates around scannability, social proof, and upsell placement informed by hotjar session recordings.
Strict Performance Budget
Enforced a JS budget per section with lazy hydration, deferred third-party scripts, and custom image loading strategies.
The toolkit.
What's live.
The outcome.
Measured across launched storefronts post-redesign.
From improved IA and cart drawer upsell placement.
Mobile LCP reduction vs previous legacy theme.
Sustained high speed rating on PDP and collection templates.
Brand teams now ship merchandising changes themselves on custom themes that load fast, convert higher, and scale seamlessly with catalogue growth.
