E-commerce that sells

Checkout friction is measured - every extra field costs conversions.

Mobile checkout is designed first; most Polish and EU traffic is on phones.

I test payment sandboxes end-to-end before you accept real orders.

Polish stores: PLN, VAT invoices, InPost parcels and BLIK where supported.

US stores: USD, sales tax hooks and Shopify Markets configuration.

Technical overview

How I build and maintain online stores

E-commerce work centers on catalog, checkout, payments and order sync. I implement Shopify, WooCommerce, Magento or custom Laravel carts, and I test payment flows in sandbox before the first live order.

Shipping connectors, ERP or warehouse sync, product feeds for Google Merchant and Meta Catalog, abandoned-cart hooks and B2B price lists keep operations running. Checkout friction is measured carefully: every extra field costs conversions, especially on mobile.

Coupons, tax rules and multi-currency catalogs need edge-case coverage - expired sessions, double-submit on pay, stock changes mid-checkout. Sessions and search layers stay tuned so browsing remains fast as the catalog grows.

Common e-commerce tasks I help with

  1. How to connect online payments without double charges
  2. How to simplify checkout on mobile without losing required fields
  3. How to sync orders and stock with an ERP or warehouse system
  4. How to generate product feeds for Google Merchant and Meta Catalog
  5. How to set up abandoned-cart emails that respect consent rules
  6. How to add B2B price lists and customer-specific discounts
  7. How to integrate shipping rates and label generation
  8. How to handle out-of-stock items during an active checkout
  9. How to test payment callbacks in sandbox before go-live
  10. How to speed up category pages with large product catalogs

About me

I'm Viktar Liukevich

Full-stack developer · 15+ years creating web

I am Viktar Liukevich, an e-commerce developer in Warsaw. I have launched stores from 50 SKUs to thousands - Shopify, WooCommerce, Magento and custom Laravel carts with Polish payments and US Stripe flows.
The hard part is never the product grid - it is checkout reliability, ERP sync, feeds for Google Merchant and mobile conversion. I test sandboxes end-to-end before you accept real orders.
For Magento enterprise modules, paid-media creatives or dedicated CRO on high-traffic shops, I connect e-commerce partners in Poland, Europe and the USA - platform specialists and performance marketers under NDA. I remain your technical owner for the store.
