EU marketplace growth — from strategy to execution.
I help e-commerce brands scale across Amazon, Allegro, eMAG, Kaufland, and 10+ other EU platforms. 8 years of hands-on marketplace management, operations, and advertising.
Operations-first marketplace expertise
Most agencies manage your listings. I manage your entire marketplace business.
With a background spanning marketplace sales, supply chain, production, and logistics, I bring an operational perspective that goes far beyond ad spend. I've scaled a supplement and cosmetics brand across 14 EU platforms — handling everything from pricing strategy and listing quality to supplier negotiations and fulfillment efficiency.
Whether you're entering a new marketplace, struggling with conversion, or losing margin to inefficient operations, I'll identify the root cause and fix it — not hand you a report.
Audit & Strategy
Know exactly where you're leaving money on the table
I conduct a deep-dive review of your marketplace presence — listing quality, pricing competitiveness, advertising efficiency, logistics costs, and platform health. You get a clear picture of what's working, what isn't, and a prioritised roadmap to fix it.

Listings & Advertising
Listings that convert. Ads that pay for themselves.
I optimise product content for search visibility and conversion — titles, descriptions, images, A+ content. Then I build and manage advertising campaigns across Amazon Ads, Allegro Ads, and eMAG Ads to drive profitable growth, not just impressions.
Operations & Logistics
Cut costs. Protect margins. Deliver on time.
Marketplace success isn't just about the front-end. I oversee supply chain, purchasing, fulfillment, and supplier relationships to keep stock levels healthy, delivery times competitive, and operational costs under control. From production planning to last-mile delivery — I've managed it all.
8 years. 14 platforms. Real results.
I don't just advise on marketplaces — I've run them end-to-end, from listing creation to board-level operations reporting.
