Gift Registry API

Active

A headless gift-registry service powering wedding wish lists, baby registries, and more across multiple sites.

A multi-tenant registry backend that owns the hard parts of gift registries — item sources, claims, and ownership — so each consumer site only builds its own look and feel. Amazon products are first-class citizens stored by ASIN, any other https product page works as a generic link, and gift claims run transactionally so the same item is never bought twice.

Next.jsReactTypeScript

Key Features

  • Items from any store: Amazon by ASIN plus generic product links
  • Transactional claims so gifts are never double-purchased
  • Lists for every occasion: wedding, baby, birthday, holiday, and more
  • Headless API consumed by multiple frontend sites

Baby Registry

Active

A consumer baby-registry app built on the Gift Registry API: curated essentials lists, items from any store, one shareable link.

A baby registry frontend built on top of the Gift Registry API. Parents start from curated essentials lists, add products from any store by pasting a link, and share a single page where friends and family claim gifts — with the claim system guaranteeing nobody shows up with the same stroller.

Next.jsReactTypeScript

Key Features

  • Curated starter checklists of baby essentials
  • Add items from any store by pasting a product link
  • One shareable link for friends and family
  • Claim tracking that prevents duplicate gifts

A wedding-website platform: save-the-date pages, guest RSVP with party and dinner choices, and a planning dashboard on your own domain.

An earlier attempt at Orleans grain indexing using Azure Cognitive Search.
