About Me

I am an honors engineering graduate specialized in Computer Engineering. Currently, I serve as a Lecturer (Probationary) at the University of Sabragamuwa, where I bridge the gap between academic research and industrial application.

My research is driven by a curiosity for Hybrid Quantum-Classical frameworks and their application in Computer Vision and Anomaly Detection. I focus on making AI models more robust and explainable.
