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 .
