About Me
20+ projects / 3 years on Shopify / Shopify Partner
Shopify Partner with several years of experience building and growing e-commerce stores. I have completed 20+ projects — from migrations from other platforms to full store builds, custom development and performance optimization.
My background in economics means I approach each project not just as a developer but as someone who understands business. I care about whether the store is built to sell, not just whether the code works.
I work with clients from Poland and abroad. Clear communication, defined scope and on-time delivery are non-negotiable for me.

- Implementations & Integrations Building stores from scratch — payments, shipping, apps, external system integrations, technical support and bug fixes.
- PageSpeed & Core Web Vitals Store performance optimization for better conversion rates and higher Google rankings.
