At Infosys Limited, I built a real-time supply chain analytics pipeline for Procter & Gamble using Pub/Sub, Dataflow, and BigQuery, processing 2M+ events per day. I also developed stored procedures for POS data analytics.
For Walmart, Target, and Amazon, I migrated an on-premise data warehouse to GCP, ingesting 5TB+ daily into BigQuery. I designed partitioned schemas that cut query costs by 45% and dashboard load times by 60%, and automated orchestration with Cloud Composer to reduce data latency from six hours to 30 minutes.
I also built a Python-based GCP onboarding pipeline that cut onboarding time from three weeks to four days. My work has included optimizing PostgreSQL ETL, automating data validation, and resolving production incidents across GCP infrastructure.
