I lead scalable cloud data migrations and real-time analytics pipelines across GCP, AWS, and Azure.
IndiaWhat I'm looking for
At Tredence, I lead Databricks-to-GCP migration workstreams, including a 47B+ record migration completed with full data integrity. I build PySpark ingestion frameworks on Dataproc Serverless and orchestrate pipelines with Airflow.
Previously, at Comcast for Sky, I architected GCP data platforms across raw, transformation, and curated layers for mission-critical analytics. My work improved BigQuery query performance by 40%, reduced data incidents by 80%+, and delivered zero critical production failures across 12+ releases.
I build batch and real-time pipelines using BigQuery, Dataflow, Pub/Sub, Kafka, PySpark, dbt, and Airflow. I also design data quality, reconciliation, schema evolution, CI/CD, and observability practices that make platforms reliable and maintainable.
Earlier at L&T Infotech supporting Citi Bank North America, I delivered banking ETL pipelines processing 20M+ records per load with 100% reconciliation accuracy and zero data loss. I enjoy leading technical delivery, mentoring engineers, and partnering with stakeholders to turn complex data requirements into dependable products.
