- Strong experience integrating acquirers, PSPs, and payment processors
- Solid knowledge of card network rules and technical specifications
- Hands-on expertise with 3-D Secure (3DS2), Merchant-Initiated Transactions (MIT), and card-on-file / recurring payments
- Strong understanding of payment authentication data (CAVV, trace IDs, transaction indicators, etc.)
- Proven ability to debug and audit payment flows at request/response level
