Madhusudhan Venkatarangaiah

I’m a Data & AI professional with 2 years of experience and an M.S. in Electrical Engineering (Machine Learning & AI) from the University of South Florida. At Sigma Analytics LLC, I built Tableau dashboards for payer KPIs, developed SQL/Python ETL pipelines into Google BigQuery, and wrote/optimized SQL to keep reliable data refreshes for reporting and analytics.

I also built predictive models to identify high-risk patients and patterns related to claim denials, automated recurring Tableau reporting for self-service across operations, finance, and clinical teams, and implemented data validation checks to improve data quality. My background includes an ISRO internship leading phase extraction model work with custom FFT and zero-phase filtering (99% accuracy), plus projects like a 3D U-Net for MRI tumor segmentation and an in-progress clinical decision support system using Logistic Regression, XGBoost, FastAPI, Docker, and BI dashboard integration.
