   As a Data Engineer at CVS Health, I lead initiatives focused on building and optimizing large-scale healthcare data platforms to support enterprise analytics and reporting. I played a key role in the Healthcare Claims Data Lake Optimization project, designing a centralized cloud-based data lake that consolidated medical, pharmacy, and eligibility claims into a single analytics-ready environment.I developed scalable ingestion pipelines using Apache Spark and Kafka to process high-volume structured and semi-structured healthcare data with near real-time availability. Through advanced Spark tuning, partition strategies, and optimized file formats, I improved query and pipeline performance by 40%, significantly reducing analytics latency.To support production reliability, I automated CI/CD pipelines using Git and Jenkins, enabling controlled deployments, versioning, and rollback across environments. I also implemented role-based access control, encryption, and audit logging to ensure compliance with HIPAA and internal security standards.By delivering trusted, high-quality datasets to BI and analytics teams, I helped increase data adoption and usage by 60%, enabling more accurate reporting, operational insights, and data-driven decision-making across the organization.
