— Case study 03
A custom Shopify storefront without a theme-shaped ceiling
project overview
An online food store where shop management stays in Shopify while the entire customer-facing site is custom-built, distinctive, and fast.
shipped outcome
A custom, server-rendered storefront with fast search and cart shipping calculation, backed by the Shopify operations the client already trusted.
Shopify themes are quick to launch and hard to differentiate. The client needed Shopify's operational reliability for inventory, orders, payments, and fulfillment, but a storefront with full control over identity, layout, search, and performance.
The storefront is headless. Shopify remains the source of truth for commerce operations while a separate Hydrogen application renders the customer experience from Storefront API data. Checkout stays on battle-tested Shopify infrastructure instead of being rebuilt unnecessarily.

— Interface evidence
These are the verified interface captures from the project build. Scroll inside taller frames to inspect each complete page.
— Delivery process
The work is sequenced around risk. Domain rules and failure states come before interface polish; automation arrives before handoff.
Products, variants, collections, and availability rules were mapped first because the data model determines what the interface can express.
Product cards, variant selectors, search results, cart lines, and price states became reusable components before pages were assembled.
GraphQL query shape and result rendering were tuned around the search path where conversion friction is most visible.
Optimistic cart updates stay responsive while Shopify remains authoritative for lines, totals, and shipping calculations.
— System architecture
Each layer has one job and a narrow contract. That keeps external services replaceable and product behavior testable.

cart / 03
Server-rendered routes with nested data loading and commerce-aware caching.
Products, collections, search, variants, and cart mutations over GraphQL.
Server-only access for operations that must never expose elevated credentials.
Payments, tax, orders, and fulfillment remain on mature platform infrastructure.
— What shipped
The customer experience is composed from custom components rather than constrained by a purchased theme.
Route-specific GraphQL queries keep discovery payloads focused and responsive.
Customers see cart state and shipping feedback before committing to checkout.
— Engineering pressure
Each route requests only the fields it renders so catalogue growth does not inflate every payload.
Optimistic updates keep interactions immediate while server reconciliation preserves Shopify as the source of truth.
The selector prevents impossible option combinations and keeps availability legible as dimensions multiply.
