Projects

• Smart Cloud Data Protection System Using Zero Trust Architecture
  Python, Flask, AWS EC2, AWS S3, Boto3, SQLite

  Developed a Zero Trust-based cloud data protection system using Flask and AWS EC2/S3. Implemented AES-256-GCM authenticated encryption and file fragmentation for secure cloud data storage. Integrated MFA/Email OTP, RBAC, Risk-Based Authentication, IP rate limiting, brute-force protection, and account lockout. Implemented hash-chained audit logging for tamper-evident security monitoring.

• Credit Card Fraud Detection System
  Python, Scikit-learn, Random Forest, Isolation Forest, SMOTE, HTML, CSS, JavaScript

  Developed a machine learning model to detect fraudulent credit card transactions using the Kaggle Credit Card Fraud dataset. Applied SMOTE to handle class imbalance and implemented Random Forest and Isolation Forest models, evaluating performance using accuracy, precision, recall, and AUC-ROC. Built an interactive web interface using HTML, CSS, and JavaScript to classify transactions and display fraud prediction results.
