Aman Singh

I’m a Data Science and Machine Learning professional with hands-on experience across Python, SQL, Power BI, and end-to-end ML pipelines. I work confidently from EDA and feature engineering through predictive modeling, visualization, and deployment.

In my current role as a Data Science Intern at OPTI BOT Pvt Ltd., I built an automated stock data collection pipeline using Python, Pandas, APIs, and SQL to support analytics and ML workflows. I also led independent data cleaning, preprocessing, and EDA in a remote setup, reducing data quality errors and documenting findings for async team review.

I’m especially strong in delivering outcomes on structured and unstructured datasets, including classification and regression models. My work includes designing interactive dashboards for company-wise analysis and historical trends, plus predictive reporting for business intelligence and financial analysis.

My projects reflect my focus on practical performance and clear collaboration: a fraud detection system with 95%+ F1-Score using SMOTE, an NLP spam classifier with 98% accuracy, and a heart disease prediction pipeline achieving 99% ROC-AUC across multiple models.
