At Lampenwelt GmbH, I engineered 30+ Databricks pipelines processing daily sales and marketing events, and cut a core pipeline’s runtime from 24 hours to about one hour. I also built dimensional models for self-serve QuickSight dashboards and KPI reporting.
I designed data connectors and a multi-terabyte pipeline, and built DBT data-quality tests and alerting that reduced analyst rework by about 30%. I also implemented GDPR-related access controls in Databricks Unity Catalog and mentored data engineers on DBT modeling and pipeline design.
