Arbitrack's Product Finder connects via API to a third-party tool built for a broader audience with 120 filters, most of it noise for merchants. Redesigned from a cramped modal into a scalable page with 15 MVP filters, a consistent field system, and key features made discoverable.

Inherited a partially-built library and rebuilt it with token architecture, component documentation, and an adoption strategy across 5 products and 50+ engineers. Dev timelines shortened ~25%; design comment threads dropped ~70%.

Designed RYVYL's first consumer product from discovery through delivery: an iOS and Android wallet for European users managing multi-currency accounts, cross-border transfers, and physical and virtual cards.

[Designed a Banking-as-a-Service platform from nothing: multi-currency accounts, cross-border payments, and a compliance-heavy operations portal for the businesses running on top of it.]

[Designed the merchant mPOS tools and the consumer app on the receiving end. B2B and B2C in the same transaction, each with its own mental model.]
