I build headless Shopify storefronts with Next.js and custom Liquid themes that go far beyond what standard templates offer. Checkout extensions, private apps, Storefront API integrations, and 90+ Lighthouse scores — designed for conversion and speed.

Custom Next.js frontend connected to Shopify Storefront API. ISR product pages, real-time cart, and sub-1.5s loads.
Bespoke Shopify themes built to your design — no template constraints, full section schema, and optimised Liquid code.
Shopify Checkout UI Extensions for custom fields, order bumps, loyalty points, and delivery date selection (Plus).
Deep Storefront API integrations including custom filtering with metafields, dynamic product bundles, and B2B pricing.
Custom private apps for inventory sync, custom order workflows, ERP integrations, and automated fulfilment triggers.
Auditing and optimising existing Shopify stores — Core Web Vitals, image optimisation, critical CSS, and script deferral.
Headless Shopify separates your storefront frontend from Shopify's backend. You keep Shopify for inventory, orders, and payments — but build a custom Next.js frontend instead of using a theme. It's worth it when you need custom UX that themes can't deliver, sub-1.5s page loads, advanced filtering, or integration with other systems.
Not necessarily. Most Shopify apps work via the Storefront API or webhooks and continue to work headless. Apps that inject scripts into theme liquid files won't work, but most critical apps (reviews, loyalty, analytics) have API-based alternatives or headless-compatible versions.
In production headless builds I typically achieve 90–96 Lighthouse performance scores. The gains come from eliminating theme JavaScript overhead, serving pre-rendered HTML (ISR/SSG), and fine-tuned image optimization via next/image. One recent migration went from 48 to 96.
Yes. I build Shopify Checkout UI Extensions — custom UI components that run natively inside Shopify's checkout — for order bumps, custom fields, delivery date pickers, loyalty point displays, and more. These work on Shopify Plus plans.
A complete headless storefront — product/collection pages, cart, search, account area — typically takes 6–10 weeks depending on catalogue size and complexity. Migrating from an existing theme is faster. I provide a fixed timeline in the proposal.
