What I'm looking for

I'm looking to build scalable data pipelines, trusted analytics datasets, and automated reporting that improve operational efficiency and support data-driven decisions.

At Shadowfax, I build end-to-end air freight cost pipelines from operational data ingestion through Snowflake, dbt reporting layers, and Power BI monitoring. I reduced pipeline runtime from about 40 minutes to about 6 minutes using incremental loads, watermark-based deduplication, and Snowflake MERGE logic.

Previously at Flipkart, I maintained PySpark ETL jobs on Azure Databricks processing 50M+ daily inventory and logistics records, unified data from 10+ operational systems, and reduced silent data failures by 80% through Great Expectations and Airflow alerting. I enjoy turning complex operational data into reliable, BI-ready datasets that support finance, supply chain, and planning decisions.
