IndiaWhat I'm looking for
I’m a Senior Data Engineer with 4.5+ years of experience designing, building, and optimizing scalable data pipelines and enterprise data warehouse solutions across AWS and Oracle Cloud environments.
I’ve led large-scale ETL development, data migration, and performance tuning using PySpark, SQL, and cloud-native services like AWS Glue, S3, and Redshift—helping teams improve pipeline efficiency, query performance, and decision-making.
In my current role at Oracle Cerner, I’m driving end-to-end migration of telemetry-derived datasets and ETL pipelines from Vertica to Oracle Autonomous Database, ensuring zero data loss through end-to-end validation and reconciliation.
Previously at Infosys, I built batch and streaming ETL pipelines for multi-TB risk and financial analytics, improved reliability with failure handling and retry mechanisms, and strengthened observability in Grafana—working closely with cross-functional teams in Agile delivery.
