Message

At Allianz Technology, I design and maintain Azure data platforms and build Data Vault 2.0 and dimensional models for enterprise reporting and analytics. I also develop metadata-driven ELT pipelines and reusable PySpark transformation frameworks.

Previously, at WPP MEDIA, I led a migration of legacy Oracle and SQL Server workloads to an Azure Databricks Lakehouse, delivering around 40% faster end-to-end processing. Across roles at Grover and LGIM, I’ve delivered batch and streaming pipelines, cloud data platforms, and data warehouse solutions using Azure and AWS.
