01. About Me

I'm a Computer Science student at the University of Toronto (graduating Apr 2025), with a 3.95/4.00 GPA and recognition as a Dean's List Scholar and Chancellor's Scholarship recipient.

I've had over 20 months of experience in software. Most recently, I was an AI Infra Engineering Intern at Meta, where I optimized model processing pipelines for Instagram & Ads at scale.

My interests span ML infrastructure, distributed systems, and full-stack development. Outside of engineering I was a Undergraduate Researcher exploring explainable AI & logical ontologies as well as a Teaching Assistant for 'CSC207: Software Design'.
