European Marketplace Operations Expert

Marketplace Onboarding and Operations Expert
I help brands and agencies launch, manage, and scale across European marketplaces — including Amazon, bol.com, Douglas, Kaufland, Fnac, Rakuten and selected regional platforms.

I step in when marketplace operations become complex, performance slows down, or senior operational ownership is needed without hiring full-time.
