Enterprise Data Warehouse

A cloud-native data warehouse project built to demonstrate end-to-end data engineering skills — from raw ingestion to business intelligence. The system consolidates multiple siloed data sources into a single source of truth using modern open-source tooling, enabling reliable analytics and executive reporting without expensive proprietary platforms.

The Challenge

Most organisations sit on mountains of data spread across disconnected systems — spreadsheets, transactional databases, SaaS exports — with no unified layer for analysis. Building a production-grade warehouse that is affordable, reproducible, and maintainable by a single engineer is a non-trivial challenge that this project directly addresses.

The Solution

Results & Impact

• Consolidates multiple data sources into a single analytical layer
• Fully automated ETL pipelines with scheduled Airflow DAGs
• dbt models with built-in data quality tests
• Interactive dashboards surfacing business KPIs in real time
• Entirely free and open-source stack — no vendor lock-in
