What I'm looking for

I'm looking for remote Data Engineer work where I can solve difficult data problems, build ETL platforms and analytical warehouses, optimize data systems, and lead or mentor engineers.

At OZON, I build ETL processes and an analytical warehouse for warehouse systems using Python, PySpark, Scala, Airflow, ClickHouse, S3, and Kafka. I created an Airflow-based ETL framework that cut new pipeline development time by about 60%, and optimized ClickHouse storage and SQL to reduce cluster resource consumption by about 43% while speeding queries up 1.7x.

Previously at Sber and Yves Rocher, I developed and monitored ETL pipelines, DWH systems, dashboards, and CRM and marketing interfaces. I enjoy taking on tough data problems, from data modeling and platform migrations to mentoring engineers and improving team delivery.
