• Redesigned event driven data integration platform to handle deliveries to S3, GCS, BQ, Snowflake,Databricks, Azure for idempotency with high resilience, fault tolerance, scalability, and multi-tenancy
• Improved latency of data integration platform by 88% (1.5 hr to 10 min) for Snowflake deliveries
• Reduced query latency of real-time customer data health notifications from 8 seconds to 800milliseconds using Debezium and Postgres
• Implemented robust error classification between Airflow pipelines and major data warehouse/cloud dataintegrations, streamlining DataOps response to escalation events
• Spearheaded stabilization and code quality effort across high volume services by adding CodeCov,PMD, Spotbugs in CI/CD pipelines.
• Increased platform observability by implementing Rollbar error-tracking and tag-based cloud loggingintegration to meet product's zero missed deliveries initiative and correlate events across product
