I'm a freelance payments consultant helping companies optimize their online and POS payment processes.
With over 25 years of experience, I combine deep technical expertise with strategic thinking and pragmatic problem-solving. My core competencies include:
  • PSP selection & migration: RFP preparation and execution including EU public tenders, vendor evaluation, contract negotiation
  • Fraud & risk management: Pattern analysis, rule parametrization, 3D Secure strategy, transaction monitoring, and liquidity consulting
  • Payments data analytics: Deep-dive analysis of conversion, fees, fraud patterns, and process issues using SQL and raw transaction data
  • Product management: End-to-end payment solutions from checkout to reconciliation, with focus on outcome over output
  • POS & SoftPOS: Product and rollout management for POS and SoftPOS solutions
  • Subscription & recurring billing: Renewal rates, churn, account updater, network tokens
  • Process optimization: Automation of manual workflows, especially in reconciliation and operations
  • Technical consulting: Close collaboration with development teams on payment gateway integration, API implementation, and 3DS optimization
  • Generative AI: Analysis, prototyping and workflow automation
Before freelancing, I held payments roles at ClickandBuy, arvato financial services, XING, and SoundCloud, always responsible for payments, fraud, and billing. Working at the intersection of business and technology, I bridge the gap between requirements and technical implementation.

As Co-Founder of FAN Network, I organize payments industry events in Berlin, Hamburg, Düsseldorf, Munich, and Amsterdam. Through PreAuth Academy, I offer payments training and courses.

Selected clients: Picanova, Global Payments, Veo Technologies, EnBW, Autoscout24, zooplus, Deutsche Bank, BMW Group, TUI Group, MyTheresa, Fielmann, GetYourGuide
