What I'm looking for

I’m looking for remote role.

At Aetna, a CVS Health company, I architected the Enterprise Clinical Authorization & Claims Intelligence Platform, unifying claims, prior authorization, eligibility, provider, member, benefits, and FHIR/HL7 clinical data into AI-ready enterprise data products.

I design scalable batch, streaming, and ELT platforms with AWS, Databricks, Spark, Delta Lake, Snowflake, Kafka, dbt, and Airflow. I also establish DataOps, governance, security, and quality standards that support HIPAA compliance, trusted analytics, machine learning, RAG-based retrieval, and clinical decision support.

Previously at IBM, I built enterprise data platforms and multi-terabyte pipelines for centralized reporting, business intelligence, customer analytics, and operational insights. I lead modernization initiatives, mentor engineers, and translate complex business requirements into durable cloud-native data solutions.
