At Kantar Worldpanel, I optimized legacy Spark pipelines, cutting processing time from 52 hours to 1 hour and monthly platform costs from $30,000 to $5,000. I also refactored the cloud data architecture, reducing storage costs by 70%.
At DEUS, I architected and migrated legacy infrastructure to a Medallion data platform on AWS and Databricks. I engineered ingestion pipelines for terabyte-scale data and established data governance with Unity Catalog and Delta Sharing.
At BMW GROUP, I designed an API ingestion framework that processed 2.5 million requests and introduced Apache Iceberg to the project. Earlier, as a Data Analyst at Continental Mabor, I developed Power BI reports and used statistical analysis to identify root causes of tire defects.
