What I'm looking for

I'm looking to build scalable data platforms and intelligent data products, applying Python, SQL, Spark, Databricks, and SAP technologies to reliable analytics and machine learning workloads.

At SAP, I build hybrid data platforms with SAP Datasphere, SAP Databricks, and SAP HANA Cloud. I develop scalable ETL/ELT pipelines using SQL, Python, PySpark, and Spark SQL for high-volume structured and semi-structured data.

Previously, I built data pipelines and Tableau reporting at IQVIA and automated reporting workflows at Accenture. I also develop cloud-native SAP applications, integrate AI capabilities, and improve data reliability through CI/CD, monitoring, and performance tuning.
