Google Shopping & pMax Strategist Needed

My Shopify store (Mollie gateway) sells a rotating mix of drop-shipped products across the DACH and Benelux regions, and I need an ads specialist who can turn data into sales. The single most critical piece is the hands-on setup and ongoing optimisation of Google Shopping and Performance Max campaigns; everything else supports that goal. Here’s what I expect: • Build, structure, and scale Shopping and pMax campaigns with Europe-specific feeds, localised assets, and a clear ROAS target. • Map out a low-budget product-testing routine that quickly flags winners and cuts losers before real money is spent. • Deploy or refine GA4, Google Tag Manager, and Google Ads conversion actions so every cent of ad spend is fully tracked. • Provide concise weekly insights: what you tested, what you’re killing, and what you’re doubling down on. To hit the ground running, please tell me: 1. Examples of European e-commerce accounts you have grown, preferably in DACH or Benelux. 2. Your step-by-step testing framework for new products on limited budgets. 3. Any quirks you’ve encountered with Shopify + Mollie in Google Ads tracking—and how you fixed them. If your experience matches those points and you thrive on hitting sales targets, I’d love to see your approach.
