About me

I'm a Computer Science student at McMaster University who loves turning ideas into working software. I spend most of my time building things — web apps, ML models, and developer tools — and chasing the satisfaction of making complex systems feel simple.

Lately I've been deep in applied AI: retrieval-augmented generation, full-stack AI assistants, and the engineering that makes them fast and reliable. I care about clean code, good UX, and shipping things that actually get used.

Outside of coursework I'm usually exploring a new framework, contributing to side projects, or playing chess.
