Since 2010, I've been working on an e-commerce engine called Kostizi that powers online stores for multiple publishing partners, including Salt Lake City Weekly (https://cwstore.cityweekly.net). I've been using ColdFusion in the Coldbox framework for that entire time.

Recently I've started building an API service for Kostizi that serves nothing but JSON, to be used by platform-specific mobile apps, and potentially things like Wordpress integrations. I'm building this service using Node.js and the Express framework, which I'm trying to learn as I go along.
