What I'm looking for

I'm looking for open-ended, cross-team data problems where I can turn raw and ambiguous inputs into reliable pipelines, analytical datasets, and decision-ready products.

At eMAG, I build end-to-end data pipelines and curated datasets for critical business decisions, including near-real-time stock visibility, profit KPIs, price indexing, and supply-planning solutions. I use Python, PySpark, Spark SQL, dbt, Iceberg, Airflow, and Tableau to make multi-billion-row data reliable and usable.

Previously, I improved analytics performance and data quality at METRO.digital, built insider-threat detections at Amazon, and developed machine learning data-processing systems at Nuvei. I enjoy turning ambiguous cross-team problems into dependable data products, and I also mentor junior colleagues.
