At Evercode Lab, I built a corporate PostgreSQL-based DWH from scratch at tens-of-terabytes scale, integrating dozens of sources and hundreds of tables. I design data marts and dedicated databases for BI, operations, engineering, and management reporting.

I build and monitor ETL/ELT pipelines, data-quality checks, and production-ready data processes using SQL, PostgreSQL, Python, Airflow, dbt, Kafka, and Spark. I also optimize large-volume workloads, document systems, review code, and mentor junior specialists.
