About Me

I'm passionate about data analytics and using data-driven insights to solve real-world problems — exploring datasets, building predictive models, and uncovering meaningful patterns.

With experience in predictive modeling, customer segmentation, and statistical analysis, I've worked on projects from medical insurance premium prediction to churn analysis, translating technical findings into business value. Alongside analytics, I build focused, offline-first web apps.
