Scaling Shopify and ChannelAdvisor for High-Volume E-Commerce: 1.6M Products, Custom Code, and Automation

Project Overview

I managed and maintained a Shopify-based e-commerce platform with over 1.6 million products, integrated with ChannelAdvisor for multichannel distribution across Amazon, eBay, Walmart, and internal systems. My role focused on ensuring data accuracy, synchronization, and platform scalability.

I implemented SearchSpring for advanced product filtering, sorting, and search functionality, and contributed custom HTML/CSS/Liquid code across the storefront to enhance the user experience. I also built internal tools to automate tasks like data updates, tagging, price syncing, and catalog cleanup — significantly reducing manual labor and errors.

This work played a major role in optimizing the operations of PlumbingOverstock.com and its associated brands.

Skills Used:

  • Shopify theme development and Liquid customization
  • ChannelAdvisor integration and marketplace feed management
  • SearchSpring setup for smart filters, facets, and search logic
  • Custom HTML/CSS/JavaScript for storefront features and UI fixes
  • Product catalog management for over 1.6 million SKUs
  • Automation scripting for product updates, tagging, and cleanup

How I Can Help Your Business:

  • Scale your Shopify store to handle large product catalogs efficiently
  • Integrate multichannel tools like ChannelAdvisor for marketplace selling
  • Implement advanced product discovery with SearchSpring or similar tools
  • Build custom storefront features using HTML, Liquid, and JavaScript
  • Automate time-consuming catalog management tasks

If you’re running a large or fast-growing e-commerce business, I can bring structure, automation, and performance to your operations while building custom solutions that scale with you.
