whocards.cc

Owned conversation card product: an Astro + Stripe storefront with automated fulfillment, and an iOS app shipped in 14 languages — built end to end as the only technical person.

Problem

The product needs more than a fast storefront: it has to make the cards feel intentional, support a smooth checkout flow, coordinate shipping operations without manual overhead, and carry the same game onto a phone.

Role

Co-founder / Sole Engineer

What Avi built

Co-created the product, shaped the product design, built the Astro storefront and Stripe payment flow, integrated fulfillment across two shipping providers, then shipped the WhoCards iOS app (Expo / React Native) from a pnpm + Turborepo monorepo where web and mobile share a headless play engine, tRPC API, and design tokens.

Outcome

whocards.cc is an ongoing owned product with ~600 orders fulfilled and a live iOS app in 14 languages including RTL, released through an automated EAS build-and-submit pipeline with over-the-air updates. Android is in closed testing.

Commerce work is strongest when the site feels simple and the operations underneath are boring in the best way. whocards.cc is ongoing owned product work, so the project includes product design decisions, the buying experience, fulfillment logic, and the operational details of working with two shipping providers.
