          Implemented a Heart Drug Target Detector to identify drug targets from 1.4 billion candidates, achieving a precision score of 0.91.

          Led a team of 3 data scientists to extract data from 8 million articles, using NLP and LLM techniques for feature generation. Applied feature selection with Boruta and mRMR, trained models (Logistic Regression, Random Forest, XGBoost, SVM, CNN), and deployed the model as a Flask app on AWS.

          Developed a Heart Attack Detector using health data, achieving a recall score of 0.81.

          To identify high-risk individuals for heart attacks, I integrated data from a local hospital database and web scraping. Derived features using historical survival analysis models and trained multiple classification models, including KNN, XGBoost, and Artificial Neural Networks.
