Medical Insurance Fraud Detection
One impactful project was Medical Insurance Fraud Detection, where machine learning models were applied to millions of healthcare records. The analysis uncovered fraud patterns with high accuracy, showing the potential to save billions in healthcare costs.
This project strengthened my ability to work with big data, feature engineering, and model evaluation, while also teaching the importance of balancing accuracy with recall to address real-world risks.

Project Approach
Every new data analysis project begins with understanding the business problem and defining clear objectives. I then focus on data collection, cleaning, and exploration to ensure quality and reliability. Using the right tools and techniques, I apply statistical methods, visualization, and predictive modeling to uncover meaningful patterns.
Finally, I translate results into actionable recommendations with clear visualizations and concise storytelling, ensuring stakeholders can make informed decisions.
