Shopify Development Open for builds

Shopify stores,
built to convert.

From headless Hydrogen builds to custom Liquid themes and the odd rescue mission — I build Shopify stores that load in under a second and turn browsers into buyers. No bloated apps, no theme spaghetti.

— Conversion rate optimization

More revenue from the
traffic you already have.

A fast store is step one — CRO is how it actually sells. I run data-driven tests on your product pages, cart and checkout to turn more of your existing visitors into buyers. Same traffic, more orders, no extra ad spend.

— My approach

How a build actually goes.

Audit & strategy

01/04

A Lighthouse audit and a funnel review, then a plan tied to revenue — not vanity metrics.

Design & build

02/04

Theme or headless, built mobile-first with clean, documented, reviewable code.

Speed & QA

03/04

Real-device testing, a performance budget, and a checkout that survives the edge cases.

Launch & grow

04/04

A zero-downtime cutover with redirects and analytics in place — then we iterate on data.

— Shopify FAQ

The questions
I usually get.

Headless or a regular theme — which do I need?
+

Most stores don't need headless. If a fast, well-built theme gets you there, I'll say so. Headless earns its keep once you've outgrown Liquid or want a fully custom front end — I'll be honest about which side you're on.

Can you work with my existing theme?
+

Yes. A lot of the work is improving what's already there — speed, bug fixes, new sections — without a full rebuild.

How long does a Shopify build take?
+

A focused theme build is usually 3–6 weeks; a headless storefront, 6–10. You get a real timeline after a short scoping call, not a guess.

Do you handle migrations?
+

WooCommerce, Magento, BigCommerce or a legacy Shopify theme — I migrate products, content and URLs with redirects so you don't lose rankings.

Will it actually be fast on mobile?
+

That's the whole point. Most store traffic is mobile, so I build to a performance budget and test on real devices, not just a fast laptop.

What happens after launch?
+

I don't vanish at handoff. You get docs, a clean repo, and support options if you want a hand once it's live.
