Academic & research
Education
BSc in Information Technology
2019Covered software engineering, database systems, algorithms, distributed systems, mobile development, machine learning, software architecture, security, user experience, and programming fundamentals throughout coursework.
Research & publications
An Enhanced Networked Traffic Light System and Traffic Flow Prediction Using Machine Learning
2019A smart traffic light system using Google Maps and cameras with neural networks to manage congestion across six junctions. Two algorithms process real-time video and traffic data: one reduces congestion locally, another optimizes network-wide flow, exposed through a REST endpoint for optimal routing recommendations.
