At Mar Symantech Private Limited, I build and maintain Python and SQL ETL/ELT pipelines that load production data into cloud databases and warehouses. I apply cleaning, schema validation, and deduplication checks to support reliable downstream analytics.
I also schedule and monitor batch jobs with Airflow and cron, investigate pipeline failures, and improve SQL transformations using indexing and execution-plan analysis. My work includes preparing analytics-ready data marts and semantic layers, with documented data definitions and lineage.
In my engineering projects, I implemented and tested CDC workflows for a cloud-native lakehouse, including ordering, deduplication, idempotency, and checkpoints. I also built a real-time EV fleet data platform and a Streamlit analytics dashboard, applying Kafka, Spark, PostgreSQL, and Isolation Forest.
