Zeproc operates a Magento-based two-sided marketplace serving European industrial buyers and suppliers, aggregating 89 suppliers and 200,000+ SKUs across drop-ship and stocked inventory models. When I joined, discoverability and conversion were lagging regional competitors, and supplier onboarding was a friction point that slowed catalog expansion.
Buyers struggled to find relevant SKUs in a vast catalog. Search ranking and category structure had not kept pace with catalog growth. Suppliers needed structured product content (titles, descriptions, attributes) to rank well, but most lacked the resources to produce it. On the buyer side, checkout drop-off was higher than industry benchmarks.
I led product across three fronts: discovery, conversion, and supplier operations. For discovery, I benchmarked competitor marketplaces, redesigned search and category surfaces in Figma, and defined feature requirements for ranking, filtering, and faceted navigation. To solve supplier content gaps at scale, I shipped an LLM-driven content generation pipeline that produced SEO-ready titles and descriptions from raw supplier attributes, lifting platform discoverability by 75% and engagement by 25%.
On the conversion side, I ran A/B tests in Adobe Target on checkout and category pages, analyzed behavioral data, and rolled winning variants into the roadmap, driving a 20% conversion lift. To tighten delivery, I overhauled backlog hygiene, surfaced risks earlier in refinement, and instituted pre-release UAT checkpoints on both the frontend and the API to catch data-structure issues end-to-end, cutting production incidents by 30%.
I shipped six large features per quarter at a 90% on-time launch rate (against a four-per-quarter target) by aligning marketing, ops, and data on launch scope and managing cross-functional dependencies. I used Clarity PPM for supplier portfolio management and built Salesforce dashboards for the AE team to track supplier-side pipeline health.
Measured. Documented. Repeatable.
"B2B marketplaces win on catalog quality, not catalog size. The LLM content pipeline was the highest-leverage investment because it compounded: every supplier we onboarded got better content, better ranking, and better conversion without proportional human effort. The hardest part was earning supplier trust to let us own their product copy.
