About

I build and scale payments and finance products across B2B (SaaS) and B2B2C (marketplace), specializing in payment service providers, payment methods, authorization optimization, and revenue growth. I lead end-to-end product development — from strategy and discovery to delivery and optimization — collaborating with engineering, design, data, finance, legal, and marketing to ship user-centric experiences. My work relies on leveraging qualitative and quantitative insights to identify and size opportunities, and running experiments to validate hypotheses and assumptions. Inspired by industry leaders like Elena Verna, Enzo Avigo, John Cutler, and Leah Tharin, I love to continuously learn by working on new, challenging problems.

      Within the Payment Solutions team, I focus on maximizing Total Payment Volume (TPV) and ensuring merchant income security across five core markets (US, PL, ES, FR & UK). Our team owns the main online payment methods, Deposits and Cancellation Fees. My work involves applying continuous discovery (interviews, surveys, CS ticket analysis) to define goal- and data-driven, quarterly roadmaps. I collaborate with a full-stack engineering squad (BE, FE across Android, iOS, & Web) on everything from goal definition (such as authorization rate, conversion rate, and adoption) to Scrum ceremonies. A key focus is testing core hypotheses through A/B testing to deliver measurable impact.
