About
A practical, technical e-commerce partner
Behind Semexpert is 15+ years of hands-on e-commerce. Day to day I work as an e-commerce director at a Polish beauty-products wholesaler - responsible for sales, marketplaces, product data, analytics and technical projects. That operational experience, combined with real technical skills, is the foundation of how I help clients.

What makes my approach different
A practitioner, not a presenter
I run e-commerce daily at a beauty-products wholesaler. I advise from the seat of someone who is accountable for the results.
Technical + business
I combine technical skills with an understanding of sales, margins, marketplaces and operations. That mix is rare - and it's the real value.
E-commerce first
I'm not a do-everything agency. I focus on data, automation, analytics and integrations for online stores.
