Freelancer profile translated to English.

Description

I am a Shopify developer focused on custom theme development, backend integrations, and e-commerce automation. With experience in Liquid, Node.js, Python, and REST APIs, I help online retailers not only make their shops look good but also run them smoothly.

I understand the challenges of daily shop operations from my own experience and develop solutions that are truly practical. Whether it's custom checkout logic, API connections, warehouse and order automations, or integrations with systems like OXID eShop and Dreamrobot – I'll find a way.
