Shopify development studio · Cluj-Napoca, Romania
Custom Shopify builds for stores with real business logic.
We build themes, features and apps for larger, multilingual stores, and connect them to the ERP and back-office systems behind them.

Projects our team has delivered
These projects were delivered by our founder in previous roles at aiconomy AG and WebGurus. The storefronts listed are publicly launched.
Confiserie Sprüngli
Rebuilt the brand's existing site design on Shopify's Dawn theme: product and collection pages, tabbed product information, a desktop mega menu and a mobile navigation drawer.
spruengli.chChrüterhüsli
A server-side wishlist on a Shopify app proxy, so saved items live outside the browser. Also a contact flow, the collection template and DE/EN translations on the Horizon theme.
chrueterhuesli.chBruderer
A custom faceted filtering layer on top of an external search service, built from product metafields. Allergen names are normalised so the same filter works across German, English and French.
bruderer.chAl-Ittihad store
Frontend work on a custom product configurator for the club's Shopify store.
ittihadclub.saArt of Fire
Tag-driven price visibility: the client hides the price of any product just by tagging it in the Shopify admin, on product pages and collection listings alike, with no code change per product.
artoffire.chMulti-store content sync
An admin app that keeps content in sync across a client's multiple stores: metaobjects, metafields, menus, blogs, pages and translations. Includes safe handling of reserved types, file remapping and a scheduled backfill.
Platform migration app
Imports customers and historical orders from PrestaShop into Shopify without ever notifying a customer. The guarantee is enforced by the build, with a dry run by default, resumable imports and a per-row CSV report.
US storefronts
Custom Shopify themes for US clients, including rebuilds and refactors focused on performance and maintainability.

About

REMTA Digital is a software company based in Cluj-Napoca, Romania. We work on larger, multilingual Shopify stores where custom business logic and system integrations matter.
Our founder, Emanuel Rusu, has been building on Shopify since 2023, across agencies and product companies. Beyond development, he works directly with project managers and clients: reviewing solutions, explaining trade-offs and reporting progress clearly.
- Clear communication. Plain explanations and honest trade-offs.
- Built to last. Maintainable code your team can understand.
- Careful with live stores. Safeguards, dry runs and staging first.
- Multilingual by default. Translations and markets considered from day one.
