At HagnosTech, I compare tenant and source datasets for the Walmart USA product catalog, reviewing a daily target of 480+ products and documenting mismatches. I also validate attributes for a US-market Attribute Enumeration model, processing a daily target of 2,000+ attributes according to SOP guidelines.
On my Urban Threads Order & Returns Analytics project, I cleaned and analyzed 10K+ e-commerce records to investigate a rise in return rates from 12% to 19%. I identified drivers including new customers, COD orders, and size-related issues, then recommended strategies to reduce returns by ~3–5%.
