Dermphi Shop
A custom Shopify app built for Dermphi Shop's storefront — extending beyond what theme customization alone could support.
Dermphi Shop needed custom storefront behavior that a standard Shopify theme couldn't support out of the box.
The brief was to extend the storefront with a custom app — keeping Shopify's native checkout intact while giving the team full control over the parts of the experience that needed to be bespoke.
Discover & Audit
Reviewed the existing storefront, checkout flow, and the custom behavior the client needed beyond standard theme capability.
Architecture & Planning
Scoped a custom Shopify app built on Next.js and Liquid, wired to Shopify's Storefront and Admin APIs.
Build
Implemented the custom app, storefront sections, and REST integrations in weekly shippable increments.
Launch & Support
Phased rollout with QA against Shopify's checkout, followed by a post-launch support window.
The storefront combines Shopify's native Liquid rendering for checkout-critical paths with a Next.js layer for the custom app surfaces, talking to Shopify via its REST APIs.
Standard theme customization couldn't support the client's custom product logic
→ Built a custom Shopify app so the storefront's special-case behavior lives in maintainable code, not theme hacks.
Storefront needed to feel fast and modern, not template-generic
→ Used Next.js for the custom-rendered surfaces, layered over Liquid where Shopify's native checkout needed to stay untouched.
"The custom app gave our storefront exactly the behavior we needed, without fighting the theme."
