Analyze authorization and renewal performance and implement measures to improve payment success rates. Support risk, fraud prevention, chargeback, and dispute-management initiatives. Assess payment flows and configurations across different products, adapting recommendations to each product's specific context and priorities.

Strong analytical rigor and a results-oriented mindset focused on measurable business outcomes. Fluent French, as it is the primary working language.
