Product, bundle, gift-card, subscription, and standard buy boxes had each grown their own section and schema over time. I helped drive the migration to a single Core Buy Box pipeline — one adapter output shape (common settings plus a block list) consumed by every product page — and led the audit that closed it out, tracing every legacy section reference before removing the old implementations.
Optimistic cart
Add-to-cart used to wait on the network before showing anything. Using Hydrogen's `useOptimisticCart` hook, the storefront now projects the cart update immediately — badge, drawer, and an "Adding…" state — from the submitted mutation, then reconciles with Shopify's authoritative response (pricing, discounts, inventory, cart-transform output) once it returns.
Metafield audit
Years of legacy theme fields and abandoned app namespaces made the storefront's data model hard to reason about. I ran the audit that turned every metafield and metaobject into a documented, owned field — consolidate, keep, delete, or app-owned — so future catalog work has a real source of truth instead of guesswork.
