Message

At Lucky Group, I designed and built a greenfield ClickHouse data warehouse and data delivery platform for an ad traffic arbitrage analytics platform. I led a two-person data engineering team and delivered analytical marts and Airflow pipelines for visits, conversions, revenue, and partner reporting.

I also implemented controls for locked accounting periods and built reconciliation and data quality checks between the analytics warehouse and CRM and finance systems.

At Predicto, I built a feature store using Scylla storage and a Rust backend for ML pipelines. I developed training datasets on S3 with historical feature views and worked on Spark and ClickHouse pipelines for ML engineers.

Earlier, I worked on data engineering platforms at Delivery Club / Yandex Eda, Rozetka, Ciklum — VP Insight, and SoftConstruct. My experience includes building data marts and ETL integrations, designing warehouse architecture, and contributing bug fixes and patches to Apache Airflow.
