About

Shopify developer with a frontend background.

Shopify developer with 6+ years in web development. I build custom themes and customize existing ones (Liquid, Online Store 2.0, Dawn, metafields), turn Figma designs into pixel-perfect, mobile-first stores and build product and landing pages. I set up apps and tracking (Klaviyo, Judge.me, GA4, GTM, Meta Pixel), migrate stores without data loss and keep pages fast (90+ PageSpeed). I use React and Next.js for complex UI and work with APIs, webhooks and Node.js next to a backend team.

How I work

How a store project runs.

The same five steps on every store, in an agency team or one to one with a client.

Brief

We agree on scope, design and deadline. I ask questions until the task is clear.

Build

I work on an unpublished copy of the theme with Shopify CLI and Git, so the live store stays safe.

Review

You check the work on a preview link, on desktop and mobile, before anything goes live.

Launch

I publish the theme, check payments, shipping and tracking, and run a test order.

Support

Fixes and small changes after launch, when you need them.

Nothing touches the live store until it is checked on a preview.
Next.js and React

Beyond Shopify.

Frontend work on SaaS products, internal tools and company sites, often next to a backend developer.
