At Chubb, I architect and develop insurance data solutions for policy, claims, underwriting, premium, customer, and actuarial analytics. I build AWS data lake pipelines and distributed PySpark workloads, improving pipeline processing performance by 30%+.

I also develop Snowflake ingestion and ELT frameworks, and modernize legacy workflows with Informatica IDMC and cloud architecture. That work reduced pipeline maintenance and deployment effort by 25%+.

At HighMark Health, I developed and maintained 30+ production pipelines for healthcare data, including member eligibility, claims, provider, pharmacy, and clinical information. My Azure Databricks and Spark transformations reduced batch processing time by 30%+.

Earlier, I worked as a Junior ETL Developer at Blue Cross Blue Shield Association and a Backend Developer at Molina Healthcare. I hold the Databricks Certified Data Engineer Professional, SnowPro Advanced: Data Engineer, and AWS Certified Data Engineer – Associate certifications.
