On the integrations team — shipping feature fixes across the personalizer and currently building the Customily ↔ Amazon Store integration so merchants can sync personalized products from their Customily catalog into Amazon listings.

Overview

Customily is the leading product-personalization platform for eCommerce — used by merchants on Shopify, Etsy, and WooCommerce to let shoppers customize products with live previews. I joined the integrations team in 2025.

What I do

  • Designing and shipping the Customily ↔ Amazon Store integration — mapping Customily product templates and personalization rules onto Amazon listings, syncing variants, and handling the asynchronous quirks of SP-API.
  • Fixing feature gaps across the personalizer — small, sharp improvements to the editor UX, preview pipeline, and merchant-facing admin.
  • Triaging customer-reported bugs alongside support, owning the fix from repro to release.
  • Writing migrations and small backend services where the integration needs first-party data hooks.

Outcomes

  • Amazon Store
    Integration in progress — first merchants live in pilot
  • 20+
