At PENTAGRAM INFOTECH PVT LTD, I designed, developed, and maintained ETL/ELT pipelines using Python, Apache Beam, and GCP Dataflow. I also built data validation, reconciliation, and monitoring frameworks for data quality and pipeline reliability.
On an enterprise data migration and cloud data warehouse modernization project, I helped migrate Oracle and MySQL data to BigQuery using Medallion Architecture. I automated workflows with Cloud Composer and optimized BigQuery queries with partitioning and clustering.
For a real-time customer analytics platform, I developed streaming pipelines with Pub/Sub, Apache Beam, and Dataflow to process customer events into BigQuery. The platform supported operational dashboards, customer behavior insights, and near real-time reporting.
