Wallet Provisioning at Scale

Own product backlog and B2B integration specifications for the edge applications connecting a major US card network to Google Pay and Samsung Pay — validating that a live card portfolio migration stays invisible to wallet users, while expanding the underlying specification to support international issuers.

About

I direct AI the same way I've always directed delivery.

An IIT Bombay MBA and Product Owner in digital payments, currently leading wallet-provisioning and card-migration work that connects a major US card network to Google Pay and Samsung Pay. My path has moved between engineering, pre-sales, and delivery — and outside the day job, I direct Claude Code to build rigorously engineered AI systems solo. The case studies on this site cover both: real payments delivery at work, and two AI systems shipped solo outside it.
