About Amir

I am a data engineer focused on Snowflake ingestion, Python-based Airflow workflows, SQL validation, audit tables, and clean handoffs to reporting teams. My background spans data analysis, enterprise IT support, and production data work, so I think about both the systems behind the pipeline and the people who depend on the results.
