My advanced enemy AI system for Arena of Oblivion uses Unreal Engine's Behavior Trees and C++ to create dynamic and challenging enemies. It features perception systems, complex decision-making, and adaptive behaviors that respond to player actions, enhancing gameplay immersion.

A social media platform for course reviews built with React, Node.js, and MongoDB. Features user authentication, course ratings, and a responsive design with full MERN stack integration.

Developed a VR-based training game designed to motivate physical activity through gamification. Players fight enemies using full-body movements in rhythm-based waves. Features include real-time pulse tracking, scoreboards, in-game purchases, and dynamic music. The game was tested on real users with positive results on both engagement and physical exertion.

Explored image reproduction by recreating original photos using a dataset of smaller images. Developed Python scripts to optimize the dataset based on color similarity and evaluated visual quality using SNR, SSIM, and S-CIELAB metrics. The project balanced objective metrics with subjective visual appeal.
