Featured Case Study

Automated Cross-Channel Analytics Engine

📋 Situation

A small-to-medium US e-commerce brand selling on Amazon Seller Central and Walmart Marketplace was manually exporting CSVs from both seller dashboards every week — 8+ hours of manual work — with no single view of profitability across channels. Leadership had no unified P&L, so budget decisions always lagged the numbers. Baseline performance: $220K monthly revenue with 3.6x blended ROAS.

🎯 Task

Build an automated, real-time data pipeline to consolidate multi-marketplace performance data (Amazon, Walmart Marketplace) for instant P&L tracking, cross-channel attribution, and executive decision-making. Target: Grow revenue to $290K+/month and blended ROAS to 4.2x+ within 6 months, profitably.

⚡ Action

•Deployed PostgreSQL database on Dockerized environment for scalable data storage
•Built n8n automation workflows fetching API data every 6 hours from Amazon Seller Central and Walmart Marketplace
•Engineered Python ETL scripts for SKU/catalog matching across Amazon ASINs and Walmart Item IDs, plus timezone normalization across fulfillment centers
•Integrated Looker Studio dashboard with live PostgreSQL connection for real-time executive reporting
•Implemented Server-Side GTM tracking recovering 18% of iOS 14+ attribution losses
