Hi, I'm Piotr.

I'm a Senior Data Engineer with over 10 years of experience, 8+ of them on Google Cloud. I build data platforms end-to-end with BigQuery, dbt and Dagster, and I like using LLMs to make data more useful. Currently building the data platform at Zowie.

Based in Warsaw. Outside of work: running, investing and knowledge management.
