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. At the same time, I'm pursuing a MASc in Electrical and Computer Engineering at McMaster University, under the awesome guidance of Prof. Thia Kirubarajan. My academic adventure started with a bachelor's degree from the University of Moratuwa in Sri Lanka.

Before jumping into grad school, I had the chance to work at the Speech and Language Lab at Nanyang Technological University with the great Prof. Chng Eng Siong. I also teamed up with Aaivu at the University of Moratuwa, working with Dr. Uthayasanker Thayasivam. My journey also includes fun experiences at Expert Intelligence, Inc., ExentAI, Ltd., and the University of Galway.
