Flagship
🚀 Walmart Data Engineering Project | End-to-End AWS & Snowflake Pipeline
An end-to-end retail pipeline built on synthetic data. Point-of-sale transactions in PostgreSQL and inventory in MongoDB are extracted by arrival time. Every store-day is reconciled against the store's close report, and daily sales and inventory KPIs are MERGEd into Snowflake. The local reference is verified by 12 passing tests; the AWS and Snowflake code is supplied but not yet run in the cloud.
