As a Data Science Intern at PreludeSys India Pvt Ltd (May 2024 – Jun 2024), I developed and optimized predictive models to assess credit risk for both loan defaulters and credit card applicants. I leveraged the Synthetic Data Vault (SDV) to generate synthetic datasets, effectively addressing data imbalance issues and enhancing model generalization. Through detailed feature engineering, I identified key predictors of default behavior and trained multiple machine learning algorithms—including Logistic Regression, Random Forest, Gradient Boosting, and XGBoost—while fine-tuning hyperparameters using cross-validation techniques. This rigorous approach resulted in high-precision predictions, with F1-scores reaching 0.734 for Loan Eligibility, 0.836 for Loan Default, and 0.954 for Credit Card Default, thereby significantly enhancing decision-making for loan approvals. Tools and technologies such as Python and Scikit-learn were instrumental in ensuring the robustness and reliability of the models, contributing to more informed, data-driven financial risk assessments.

As a Data Analytics Intern at Hyundai Motor India Limited (HMIL) (Jun 2023 – Jul 2023), I modernized legacy R scripts by migrating them to Python, significantly enhancing code maintainability and accessibility for engineering teams. I collaborated with cross-functional teams to seamlessly integrate the revamped code into production workflows and designed an interactive QlikSense dashboard for real-time monitoring of Work-in-Progress (WIP) buffer counts. This dashboard streamlined production planning by providing dynamic visualizations and predictive alerts for buffer time thresholds. Through systematic analysis and optimization using pandas and NumPy, I reduced computational overhead and memory dependency, which improved runtime efficiency for high-volume manufacturing data processing. This project not only ensured 100% functional parity between the original R logic and the new Python implementations but also enabled faster debugging and scalable solutions for ongoing process optimization initiatives.
