What kind of custom development do you offer?

Custom JavaScript features, Shopify API integrations, custom Liquid sections, interactive product configurators, cart enhancements, and bespoke storefront functionality.

Do you work with existing themes or build from scratch?

Both. I can add custom functionality to existing themes or build sections from scratch using Shopify Liquid, JavaScript, and the Storefront API.

How much does custom Shopify development cost?

Projects start from $500. Complex features like product configurators or API integrations are scoped and quoted individually. Clean code, no bloat.
