About Me

The story so far

I'm a final-year CSE student at IST, Dhanmondi. My work sits at the intersection of machine learning and product building. As President and AI Instructor at the Programming Club of IST (pcIST), I run workshops, organize contests, and mentor students. I founded Qarena — an AI-powered platform that predicts exam questions for Bangladesh's National University students, validated at 7–8.5/10 accuracy against real exam papers.
