Projects

Fraud detection models

The Fraud Detection Models for E-commerce and Bank Transactions project involves developing machine learning models to identify fraudulent transactions by analyzing transaction data and geolocation patterns. By leveraging features like transaction frequency, location discrepancies, and user behavior, the models detect suspicious activities in real-time. The project also includes building deployment pipelines using CI/CD tools to automate model updates and ensure seamless integration into production, providing continuous fraud monitoring, and enhancing security for users.

Sales Forcasting

The Sales Forecasting project focuses on developing machine learning models to predict future sales based on historical data and various influencing factors such as seasonality, marketing campaigns, and market trends. By utilizing time series analysis and regression techniques, the model provides accurate sales predictions that help businesses optimize inventory, manage resources, and improve decision-making. The project also includes deploying the model for real-time forecasting, enabling businesses to adjust strategies and meet demand more effectively.
