About

I build production-grade ML systems that solve real problems, from skin cancer classification models (90%+ accuracy) to churn prediction engines that improve customer retention by 80%. With 3+ years across healthcare, finance, retail, and SaaS, I specialize in deep learning, explainable AI (Grad-CAM, LIME, and SHAP), and data pipelines processing 500K+ records. Currently finishing an MSc in Data Science while shipping medical AI research on the ISIC skin lesion dataset.
