India
Message

At LTIMindtree, I lead Spark and Databricks delivery for Citi Bank, including migrating 15+ legacy Spark pipelines and modernizing banking data workloads. The work reduced aggregation time by ~85%.

I design and support production data platforms, tuning Scala and PySpark workloads and building AWS data lake integrations. I’ve also operationalized pipelines with Airflow, dbt, and Great Expectations, and supported secure governance with Delta Lake and Unity Catalog.

Earlier, at BA Continuum Pvt Ltd, I developed Spark, Hive, and Hadoop workflows for Bank of America, including near-real-time streaming pipelines. I also migrated legacy workloads to AWS and GCP and supported data engineering work at Seyasoft Technologies as an ETL Developer Intern.
