At Amazon, I used SQL to analyze large datasets and identify trends that helped optimize pricing and promotional strategies for vendors. I worked on automating data processes with ETL pipelines and created reports in Excel to track key metrics like sales and inventory performance. I also led projects focused on improving vendor selection and pricing, collaborated with teams across marketing and operations to refine strategies, and presented insights to stakeholders to support decision-making. My work centered on using data to drive efficiency and enhance customer and vendor outcomes.
