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 16 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. Curious by default.

May 2025 – Aug 2026
Software Engineering Intern · Hydro One

Barrie / Toronto, ON
- Automated SCADA/EMS database release workflows with Perl + GitLab CI, cutting execution time from 25 to 3 minutes and standardizing a release process now in production for 1+ year.
- Built 25+ automated validation scripts for SCADA/EMS models, improving data quality and saving 10–15 minutes per ticketed task.
- Wrote a Python package that converts EMS modeling requests into GE Source-ready import files, applying voltage-based rules and eliminating manual data prep.
- Migrated a legacy FORTRAN dynamic line-rating codebase to C++, improving maintainability and removing single-expert dependency.

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

Face Cue

A real-time, on-device face-recognition aid for prosopagnosia, built in C++/OpenCV (YuNet detection + SFace 128-D embeddings) matching enrolled faces at ~8 ms/frame on CPU with no cloud, network calls, or stored video. A conservative decision layer (cosine threshold, top-2 margin, multi-frame agreement) tuned on the LFW benchmark reached 0 false matches across 1,642 stranger tests at 99.5% recall. Served from a localhost-only C++ HTTP/MJPEG server behind a React + TypeScript UI, with 15 unit tests.

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.
