What I'm looking for
I am a results-driven Data Engineer with over eight years of experience designing and implementing scalable ETL pipelines, data warehouses, and lakehouse architectures.

I deliver actionable business insights through interactive Power BI dashboards and performant data models, having reduced query latency by 40% and improved legacy ETL performance by 35%. I mentor junior engineers, design star and snowflake schemas, and drive data quality via automated validation and reconciliation while leveraging Snowflake, Databricks, PySpark, T-SQL and containerization tools to support enterprise analytics needs.
