Varun Thota

I’m a Data Analyst/Data Engineer with 4+ years of experience delivering data-driven solutions across healthcare and consulting. I build end-to-end ETL pipelines, real-time data streaming architectures, and data warehouse solutions on modern cloud platforms. At Kaiser Permanente, I architected scalable ETL pipelines processing 2.5 million patient records daily using Apache Spark and AWS Glue, cutting data processing time by 45%. I also built real-time streaming with Apache Kafka and AWS Kinesis to monitor patient vitals and clinical events across 40+ medical facilities. I strengthen reliability by implementing automated data quality validation with Python and SQL—achieving 99.8% data accuracy—and by enforcing HIPAA-compliant data governance and security measures. I optimize performance through indexing and query tuning, reducing report generation time by 60%. Previously at PwC, I analyzed 10+ million transactions monthly to identify fraud patterns and reduce false positives by 40%, and I built BI dashboards in Power BI and Tableau for 15+ client portfolios. I enjoy mentoring teams, translating complex requirements into technical solutions, and delivering insights that improve decision-making and operational efficiency.
