Abstract:

Scaling fintech products introduces a new class of problems that rarely appear at the MVP stage—payment failures across markets, fragile integrations, regulatory constraints, and checkout flows that break under real-world complexity. In this session, Sanya Engineer, Lead Product Manager at PayPal, shares real roadblocks encountered while building and scaling global checkout systems used by millions of users. The talk will break down common failure points in payment flows, why many checkout systems struggle at scale, and practical approaches to solving them.
