Top SchoolAlexander Volok is a Senior Python Data Engineer with over a decade of experience building production-grade data platforms using Python, Spark and Azure Databricks.

Recent roles at ASML, Ahold Delhaize and ABN AMRO highlight his focus on event-driven ingestion (Event Hub/Kafka), Databricks optimizations and orchestration with Airflow/ADF. He holds multiple Databricks and Azure certifications and has repeatedly led migrations and modernization of legacy BI to scalable lakehouse architectures.
