About Me

I'm a Data Engineer with production experience delivering high-scale, regulated financial workloads at TCS for Vanguard.

I specialize in modernizing legacy ETL systems — migrating mainframe/COBOL + DB2 jobs to fully serverless AWS architectures using PySpark, Glue, Lambda, Step Functions, and EMR on EKS.

Currently focused on building real-time streaming pipelines, data lakehouses with Apache Iceberg, and Kubernetes-native data platforms using Argo Workflows and Karpenter.
