At Cognizant Technologies, I analyzed Brazilian e-commerce data across orders, customers, products, sellers, payments, reviews, and delivery. I cleaned and joined datasets to prepare them for analysis.
I used SQL to examine sales trends, customer behavior, product performance, and seller efficiency. I also investigated estimated versus actual delivery dates and their relationship to customer review scores.
For digital advertising performance and quality analysis, I examined ad accuracy, relevance, landing-page consistency, and content quality. I tracked quality and productivity KPIs and prepared reports to support visibility into advertising operations.
