I’m a Data Engineer with 2+ years of experience building scalable ETL pipelines, real-time data ingestion systems, and analytics platforms. At ZS Associates, I architected a real-time ingestion pipeline for 1M+ rep interaction events, cutting latency by 98% (2 hours to 2 minutes) and enabling near real-time analytics for commercial performance tracking.

I optimize production orchestration and reliability—reducing an Airflow pipeline’s processing time by 50% (6 hours to 3 hours) and leading migration of business-critical pipelines processing 10M+ records from Azkaban to ZAIDYN. I also build quality into delivery with a config-driven UAT automation framework using Python and Playwright, and I automate client-facing reporting with Python, Pandas, and OpenPyXL. Beyond engineering, I apply AI through projects like a RAG pipeline for healthcare payer policy extraction and a published driver drowsiness detection system achieving 90% accuracy.
