Shopify developer · London
Shopify stores that are a joy to shop.
Hi, I’m Mladen — it’s pronounced Mwaden. I’m a designer-turned-developer who builds custom Shopify themes, adds new features to live stores and makes slow storefronts quick again. Fussy about pixels, tidy in the code.

Everything your store needs. Nothing it doesn’t.
Starting from a fresh Figma file? Or running a store that’s grown a little creaky? Either way, I can help.
I write the Liquid, JavaScript and CSS myself, and because I started out as a UX/UI designer, I notice the awkward bits shoppers trip over — before they ever reach your live store.

Selected work
Stores I’ve had
my hands in
From a household-name publisher to independent labels. Some I built from the ground up; others I joined to ship new features on a busy live store.
How I work
Straight to the developer.
No game of telephone.
-
We talk it through
You speak directly to the person writing the code. No account managers, no briefs lost in translation.
-
Design check, then build
I review the designs with a UX eye first, so awkward flows and missing states get fixed on paper — not in production.
-
Ship it, then sharpen it
Speed, technical SEO and accessibility are part of the build, not a line item you remember after launch.
