Roman-Leonid Yurchenko

Shopify Plus engineer for complex storefront logic, checkout extensibility, and platform-native commerce systems.

I work on Shopify problems that go beyond routine theme development — product configurators, Shopify Functions, Checkout UI Extensions, complex catalogs, performance, and maintainable storefront architecture.

Supporting app driven and native golf club configurators in one Shopify theme

Two built to order club lines needed guided configuration inside one theme, although LAB Golf depended on Hulk Product Options while Miura composed catalog variants natively.

Migrating a custom PHP storefront to Shopify on a metaobject layer

The old site's browse structure, its brand directories and style and colour indexes and editorial collection pages, had no equivalent in Shopify's product model and still had to survive the move.

Deriving feed attributes a catalog never stored

A hardware retailer needs its whole catalog in an advertising channel's schema, including the category and material attributes the product model never held as fields.

Known limits

Pagination: The catalog is served in fixed pages, and the channel must be configured with one fetch URL per page.
Derivation: Attributes are derived by ordered literal phrase matching over product text, so the first matching rule wins.
Truncation: A template cannot detect or report a response that was cut short, so a partial fetch reads as a complete catalog.
Currency: One rendered feed carries the one market and currency the storefront rendered it in.
Zero prices: Variants priced at or below zero are dropped from the feed with no record that they were dropped.
