Background

About Malgorzata Dejnarowicz

With over 14 years of experience in Financial Services and Card Payment industry, I specialize in dispute resolution, chargeback management, and card scheme compliance. At PAYONE, I work as an Analyst in Chargeback Processing & Retrieval, where I combine operational precision with data-driven insights to streamline workflows, mitigate risks, and ensure end-to-end compliance across the dispute lifecycle. I bring deep knowledge of the acquiring and issuing ecosystem, including scheme regulations (Visa, Mastercard, etc), fraud prevention, and customer-centric process optimization. My role bridges business, technology, and regulation, turning complex challenges into scalable improvements. Whether it’s analyzing KPIs and risk indicators, developing rule-based logic for dispute systems, collaborating with IT teams, or advising stakeholders, I focus on driving efficiency and delivering results that matter. Always curious, always evolving. I thrive in dynamic environments where precision, compliance, and continuous improvement go hand in hand.
