SERVICE DETAILS

I build ultra-fast headless commerce stores — Next.js App Router on the frontend, Shopify as the battle-tested e-commerce backend. The result: 99/100 Lighthouse, sub-800ms load times, complete control over design and UX without Shopify theme constraints. I implement Shopify Storefront API, server-side data fetching, and Vercel Edge Network for global CDN delivery.

Who this is for

  • Shopify stores that have outgrown their theme and want a custom design.
  • Brands with heavy mobile traffic where slow loading hurts sales.
  • Businesses selling in several countries and currencies.
  • Stores that want to combine commerce with content: blogs, guides and lookbooks.

What you get

  • A Next.js frontend connected to Shopify through the Storefront API.
  • UX design for product pages, listings, cart and checkout.
  • A headless CMS for marketing content alongside Shopify product data.
  • E-commerce SEO: Product structured data, crawl-friendly filters and sitemaps.
  • Migration from the old storefront with a 301 redirect map.

How results are measured

  • Conversion rate and cart abandonment.
  • Core Web Vitals on product and listing pages.
  • Organic traffic for product and category keywords.
  • Average order value after UX changes.

Key Benefits

100/100 PageSpeed Score — headless eliminates all Shopify theme bloat that slows your store down and suppresses Google rankings for product keywords.

Complete design freedom without template constraints — every UI element is custom-coded to your brand and optimized for your specific conversion funnel.

Technical SEO at its best: SSG for product pages, dynamic XML sitemaps, structured data (Product, BreadcrumbList, Review schemas), and hreflang for multi-language.

Shopify as the reliable backend: product management, inventory, payments, and order processing stay in Shopify Admin — you lose nothing, gain frontend speed.

Edge deployment on Vercel — TTFB under 50ms globally, automatic scaling, SSL, and CDN distribution with zero server configuration.

The Process

1

Conversion Audit & Strategy

I analyze your existing e-commerce data (if available), map the purchase journey, and define measurable conversion goals before a single pixel is designed.

2

Design System & Wireframes

I build a Figma Design System — color tokens, typography, spacing, components — and deliver high-fidelity wireframes for approval before any code is written.

3

Development & Integrations

I build the store in Next.js, connect Shopify Storefront API, configure payments, product reviews, and all marketing integrations (Klaviyo, Meta Pixel, GA4).

4

SEO Audit, QA & Launch

Full technical SEO audit, Lighthouse 99/100 validation, QA across 10+ device profiles, and a smooth cutover from the old store with 301 redirects preserving SEO equity.

Frequently Asked Questions

Can I still manage products in Shopify Admin?

Yes — the entire backend (products, orders, customers, payments) stays in Shopify Admin. I only replace the frontend. Your team doesn't need to learn any new tools.

Does it work with thousands of products?

Yes. I use Incremental Static Regeneration (ISR) for product pages — thousands of pages are pre-rendered statically, and price or stock updates propagate within seconds without a full rebuild.

How much does ongoing maintenance cost?

Vercel Pro hosting runs around €20/month for most stores. Your Shopify subscription stays unchanged. There are no hidden per-transaction fees on my side.

E-commerce SEO & GEO - How Stores Win Visibility in Google and AI Shopping

AI-driven shopping is already ~$21B in annual spend (4× YoY), AI traffic to stores grew by thousands of percent, and 83% of ChatGPT's shopping carousel data comes from Google Shopping. The complete guide: Product schema, the Merchant Center feed, AI crawler access, the ACP/UCP protocols and a store rollout plan.

JavaScript SEO - What Googlebot and AI Crawlers Really See Without Rendering

Googlebot renders JavaScript - late and at its own cost. Most AI crawlers never render it at all: Vercel's study showed GPTBot, ClaudeBot and PerplexityBot fetch JS files but don't execute them. How to check in 5 minutes what bots really see, how CSR differs from SSR/SSG/ISR, and how to fix an SPA without rewriting the whole app.

Core Web Vitals 2026 - How to Improve LCP, INP and CLS

Core Web Vitals are the three metrics of real user experience: LCP (how fast content appears), INP (how fast the page responds) and CLS (does the layout jump). I explain the exact thresholds, the common causes and concrete fixes - including Next.js levers - without chasing a perfect Lighthouse 100.
