🧠Built an end-to-end Databricks Lakehouse

🧠Built an end-to-end Databricks Lakehouse Sales Analytics demo that transforms raw sales transactions into clear, decision-ready business insights.

I configured an on-demand Serverless SQL Warehouse, ingested the Databricks sample sales dataset into a Bronze-layer table, developed reusable SQL queries and measures, and published an interactive analytics dashboard. The workflow demonstrates the complete journey from raw data ingestion to business reporting using a practical Lakehouse and Medallion Architecture approach💯

The demo analyzes 3,333 sample transactions across multiple countries, products, payment methods, customers, and franchises. The dashboard presents headline KPIs including $66.4K in revenue, 3.33K transactions, a $19.94 average order value, and 300 unique customers, together with revenue trends, product performance, country analysis, payment-method distribution, and top-franchise rankings.

I also used Databricks Query History to track SQL execution status, duration, and source across 64 query executions, providing visibility into the development and analytical workflow.

This project demonstrates my capabilities in Databricks, Lakehouse Architecture, Serverless SQL, Medallion Architecture, SQL modeling, data ingestion, KPI development, dashboard design, and business analytics.

The project was prepared as a technical demonstration using Databricks sample data and was delivered entirely on the free tier—without exposing any production or confidential client information.
