Quantitative Risk & Data Science Engineer | Monte Carlo Simulation | Machine Learning | Statistics

Profile Summary

I am a Statistics and Information Analysis Engineer with expertise in data science, machine learning, statistical modeling, and artificial intelligence. I specialize in transforming complex datasets into actionable insights through rigorous statistical analysis, predictive modeling, and AI-driven solutions. My background combines advanced statistics with practical experience in developing end-to-end data science applications across the insurance, healthcare, and industrial sectors. I have successfully designed predictive models, conversational AI systems, risk analytics solutions, and interactive dashboards that support data-driven decision-making. My recent work includes developing an extreme risk modeling framework for the insurance industry using Monte Carlo simulations to estimate Value at Risk (VaR) and Tail Value at Risk (TVaR), accompanied by a real-time monitoring dashboard for technical profitability. I have also built Retrieval-Augmented Generation (RAG) systems powered by Large Language Models (LLMs), fine-tuned language models to improve response accuracy, and developed intelligent forecasting models using machine learning techniques such as Random Forest, XGBoost, and LSTM networks. My research interests include: * Statistical analysis and hypothesis testing * Predictive analytics and machine learning * Deep learning and computer vision * Natural Language Processing (NLP) * Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG) * Quantitative risk modeling * Monte Carlo simulation * Time series forecasting * Data visualization and business intelligence * Healthcare analytics * Financial and actuarial analytics I am proficient in Python, SQL, and R, and regularly work with Scikit-learn, TensorFlow, PyTorch, LangChain, Hugging Face Transformers, FastAPI, PostgreSQL, ChromaDB, Dash, Plotly, Tableau, Power BI, and Streamlit. In addition to my professional experience, I have completed several research-oriented projects, including credit risk modeling, MRI brain tumor classification using convolutional neural networks, and business intelligence dashboards for energy monitoring. These projects strengthened my expertise in statistical inference, feature engineering, model optimization, and explainable AI. I enjoy collaborating with researchers, startups, healthcare organizations, financial institutions, and businesses seeking reliable statistical analysis, machine learning solutions, AI development, or data-driven decision support. I am committed to delivering reproducible, high-quality work with clear communication and strong attention to detail.
