Top SchoolRoman Volozhanin is a Senior Data Engineer with 8+ years building and operating large-scale distributed data platforms, currently leading a bank-wide migration from an Oracle DWH to a Lakehouse handling 1B+ daily CDC events. He designs production services (FastAPI + Postgres) for schema evolution and column-level lineage, optimizes Spark/Impala processing of terabyte workloads, and drives architectural strategy and vendor selection for multi-year platform transformations. Comfortable across the stack, Roman combines Python backend skills (FastAPI, Django) with Kafka, Debezium, Iceberg/Parquet, Kubernetes and monitoring/governance tooling to keep pipelines compliant and reliable. He mentors teams, delivers training on Spark, Iceberg and Python, and has a track record of refactoring legacy systems to improve maintainability and performance. Earlier roles show a knack for turning messy operational data into actionable systems—reducing reporting from days to hours and improving query performance by 30%.
