Don Stefani

Senior Shopify app developer & technical consultant.

I'm a senior Shopify app developer with 30+ years of engineering experience. I build custom embedded Shopify apps, Admin API and GraphQL integrations, and the AWS backends behind them — for merchants who've outgrown off-the-shelf apps and theme tweaks and need real software built right. My niche is Shopify × AWS: reliable, enterprise-grade integrations few freelancers can take on. Based in Boise, Idaho, and currently taking on new client work. Connect with me on LinkedIn.

This is the first iteration of the site — more projects, case studies, and detail are on the way.

Case Studies & Demos

Demos

• Collection Price Updater

  Bulk-update product prices across Shopify collections, safely and reversibly.

• Metafield Manager

  Create and edit Shopify product metafields in bulk with saved field sets.

Case Studies

• Bulk product create & update

  Serverless AWS pipeline that imports catalog data and creates or updates Shopify products at scale — inventory, images, and verification included.

• Store-agnostic Shopify taxonomy & category mapper

  Two-stage pipeline (rules + Claude AI) that classifies any store's catalog against Shopify's Standard Product Taxonomy and writes results back.
