I am a Senior Data Engineer and Technical Lead at Alexander Thamm GmbH, specializing in Azure-based data platforms, Databricks, PySpark, and modern analytics solutions. I design, develop, and maintain scalable data platforms, production-grade ETL/ELT pipelines, business intelligence solutions, and cloud-native applications.
Besides data engineering, I lead development teams, consult clients on technical solutions, translate business requirements into technical designs, estimate work packages, and drive technical decision-making. My experience spans data engineering, data warehousing, cloud architecture, business intelligence, and full-stack application development. Based in Berlin, Germany.
