What I'm looking for

I'm looking to architect scalable, secure, and cost-effective cloud data ecosystems, lead complex GCP data and AI/ML initiatives, and mentor engineering teams while delivering reliable data platforms.

I'm currently modernizing CVS Health's drug-data ETL, migrating Oracle workloads to BigQuery and supporting FDB's transition from DIFF33 to MedKnowledge.

I build Cloud Composer DAGs, Dataflow pipelines, BigQuery SQL, Cloud Spanner loads, and comparison frameworks that validate legacy and modernized results. I also support automated provisioning and CI/CD through GitHub Actions and Cloud Build.

At Dollar Tree, I architected GCP solutions for Customer 360 and customer data platforms, unifying customer data with serverless Apache Beam and Dataflow pipelines. I integrated Vertex AI Pipelines, Feature Store, AutoML, data-quality monitoring, Terraform, DLP, Looker, and Cloud Build into scalable retail and digital-marketing workflows.

Across SKY, Capgemini, SmartFocus, Infosys, and banking, telecom, healthcare, retail, and media engagements, I've delivered ETL, warehouse, streaming, and analytics solutions. I lead code reviews, mentor engineering teams, and bridge onshore and offshore teams to deliver reliable cloud data platforms.
