I build cloud data pipelines and validation systems across GCP, Spark, BigQuery, and Python.

What I'm looking for

I'm looking to build reliable cloud data pipelines, automate validation, and improve data operations while working closely with clients and engineering teams.

At GSPANN, I build and improve BigQuery data pipelines for Dialpad’s product-pricing requirements, automate data validation, and implemented the Self Service Amendment process for customer actions and future product data.

Previously at Pythian and Infosys, I developed cloud and Spark-based pipelines for Transat, Monumetric, and Truist-BBnT Bank. I use Python, SQL, Dataflow, Pub/Sub, Airflow, Hive, and PySpark to ingest, validate, orchestrate, and troubleshoot batch and real-time data workloads.
