Ich bin ein erfahrener Product Manager mit über 20 Jahren Erfahrung in datenintensiven B2B-Plattformen. Meine Arbeitssprache ist Englisch. Ich bin deutscher Staatsbürger und arbeite remote aus Israel als B2B-Auftragnehmer — Rechnungsstellung direkt, kein Payroll-Aufwand auf Ihrer Seite.

I take AI products from pilot to production. Most AI projects stall not because the technology fails, but because nobody defined what "working" means — no quality framework, no evaluation criteria, no path from prototype to deployed system. That's the gap I fill.

I embed with your engineering and data science teams as product leadership: defining ML model requirements (input features, output format, performance constraints), designing data models and cross-source data harmonisation logic, setting precision and recall quality gates, and driving delivery through to production.

Track record:
  1. Booking.com — 90% ML pipeline efficiency improvement. Defined precision/recall quality gates for model deployment. Reduced iteration cycles from weeks to days. Published at SIGIR 2020 and WWW 2022.
  2. EX.CO — ML-based yield optimisation engine, zero to production in six months. Defined model requirements end-to-end. Delivered 30–40% revenue uplift. Offered full-time to retain.
  3. Zalando — Built zPrice, the pricing data platform across 17 European markets. Designed the data model that harmonised tens of millions of SKUs across different naming conventions, currencies, and competitive formats. Managed 40+ concurrent initiatives.
  4. DoubleVerify — Brand safety AI PoC on a major social platform. 80% classification precision. First deployment of its kind. Offered full-time to retain.
  5. Huawei — Enterprise B2B product portfolio across EMEA and LATAM. Technical pre-sales and solution design for large-scale deployments.
Education:
M.Sc. Computer Software Engineering (Imperial College London), B.Sc. Electrical Engineering (UNICAMP, Brazil).
