About

Welcome to my personal space! Currently, I am driving next-gen AI solutions for business transformation at Iterate.ai, where we focus on building reproducible, automated, and scalable pipelines while optimizing performance, including enhancing edge computing efficiency. I completed my MASc in Electrical and Computer Engineering at McMaster University, under the guidance of Prof. Thia Kirubarajan. My academic journey started with a bachelor's degree from the University of Moratuwa in Sri Lanka.

Before pursuing my graduate studies, I had the opportunity to work at the Speech and Language Lab at Nanyang Technological University with Prof. Chng Eng Siong. I also collaborated with Aaivu at the University of Moratuwa, working with Dr. Uthayasanker Thayasivam. My professional journey includes valuable experiences at Expert Intelligence, Inc., ExentAI, Ltd., and the University of Galway.
