01. About

I'm a Computer Science student at Queen's University (Software Design specialization), graduating in 2027. Most of what I do comes down to building tools people actually reach for.

Recently I spent 15 months at Hydro One, where working directly on Ontario's power grid was honestly one of the coolest parts. On the side I help build Coursify, a course-planning platform now used by 5,400+ Queen's students. I care about the details: clean code, clear docs, and shipping things that hold up in production.

Currently working with:

TypeScript
React / Next.js
Node.js
Python
C++
PostgreSQL / Supabase
Redis
Docker

Beyond the code

When I step away from the keyboard, you'll usually find me around cars, out on the water fishing, or tinkering with whatever side project has my attention that week. Also a proud Pokémon fan, and yes, Umbreon is the best one. Curious by default.

Featured Project

Coursify

A course-planning platform for Queen's students: a Chrome MV3 extension and web app that surface GPA trends, offerings, Reddit threads, and professor reviews right inside SOLUS. 1,100+ launch-day users, now 5,400+ students. I built Redis-backed API rate limiting, Supabase Auth + PostgreSQL row-level security, and a Gemini agent grounded in course-catalog data.

Featured Project

Vision Allies · Support Hub

A Jira-style internal support hub built in React + TypeScript that centralizes issue tracking, developer follow-ups, and ticket resolution. I architected client-side state and protected navigation with Redux Toolkit and React Router, and modeled User–Ticket–Comment relationships to power contextual ticket histories and discussion workflows.
