Project 2

Southwest Airlines Database Replica

Co-Developed a robust SQL-based database system for airline operations, providing insights into staffing dynamics and improving resource allocation. Created complex queries, views, and triggers to track employee roles across flight schedules, facilitating efficient planning and decision-making.

MySQL Python
Project 2

Foodie Online shopping system

Contributed to the front-end development of an online shopping system by designing and implementing a responsive, intuitive user interface that enables seamless account registration, product browsing, and shopping cart management. Integrated dynamic features such as real-time tax calculations, discount code applications, and comprehensive order summaries, while collaborating with back-end teams to ensure cohesive integration and a consistent, engaging user experience.

Python HTML/CSS JavaScript
Project 2

MinMax Alpha/Beta ChessBot Project

Developed an AI-driven chess engine using Python, implementing a MinMax algorithm with Alpha-Beta pruning to optimize move evaluation and decision-making. Designed and integrated custom game logic for advanced chess rules, including castling, en passant, and pawn promotion. Built a local web-based interface using Flask, JavaScript, HTML, and CSS, enabling intuitive gameplay and seamless interaction between the AI and human players. Ensured efficient performance and clean code architecture, making the project a strong demonstration of full-stack development and AI implementation.

Phishing URL Detection AI Project

Developed an advanced AI-driven system to classify phishing URLs with high accuracy using Python and machine learning techniques. Engineered a comprehensive feature extraction pipeline that computes over 29 features from each URL—including address bar characteristics (e.g., URL length, redirection patterns, and suspicious token detection), domain-based metrics (e.g., domain entropy, subdomain complexity), and WHOIS-based attributes (with caching to mitigate rate-limiting issues). Leveraged ensemble and deep learning models with Scikit-Learn and TensorFlow to accurately differentiate malicious URLs from benign ones, achieving robust performance while minimizing false negatives. Integrated the system into a scalable, Flask-based web application deployed on AWS, ensuring real-time detection and streamlined user interaction—demonstrating full-stack development, advanced feature engineering, and effective AI implementation.
