Back to original languageAbout Stefan
Hi, Stefan from Hamburg here. I've been an Amazon specialist since 2016. My background: Industrial Engineering graduate, seven years in technical B2B sales, then my own FBA seller with own brands, and since 2016, a consultant for external brands and manufacturers.
Anyone who hires me works with me, not with an account team or a trainee. Direct, personal, with full senior experience.
My focus is on Amazon Advertising, the area with the most direct impact on profitability. I think in results: clean campaign structure, clear keyword strategy, disciplined ROAS and TACOS management. Advertising that matches contribution margin, not click numbers.
What I deliver:
• Amazon Advertising (SP, SB, SD): Campaign structure, keyword strategy, bid and budget control, ROAS and TACOS optimization
• Listing & Content: SEO title, bullets, backend keywords, A+ Content, Brand Store
• Account Management & Strategy: Account Health, catalog maintenance, problem-solving, growth planning
• EU Expansion: Marketplace rollouts in DE, FR, IT, ES, NL, PL, SE
Since 2016, I have supported over 25 brands in the categories Baby and Child, Garden, Beauty and Food Supplements, Bags and Backpacks, Child Safety. Some examples (categories approved, figures anonymized):
• Manufacturer in the child safety sector: Advertising account newly set up, then plus 10 percent ROAS with the same budget.
• Brand in the garden segment: Sales doubled in 12 months, holistic account takeover.
• Premium brand in the baby sector: Multi-market launch built from scratch, including Brand Store and EU cross-border.
What sets me apart: I work with AI support. Routine tasks and data maintenance are handled by my own agent system and a self-developed PPC tool. This frees up capacity for what counts: strategy, profit control, and oversight.
I currently have capacity for new projects. Just send me a message, and we'll see if it's a good fit.
