I build systems that sit between hardware, software, and everything in between. Three co-ops, a 4.0 GPA, and a habit of automating things that probably didn't need automating.
Building systems that automate, sense, and solve.
I'm a Mechatronics Engineering Co-op student at Western University with a 4.0 GPA. I gravitate toward problems that sit between mechanical design, electronics, and software. The kind that don't fit neatly into one discipline.
Across three co-ops I've built ML pipelines that boosted defect detection from 40% to 84%, developed real-time factory dashboards serving 100+ users, and implemented object detection systems on active production lines.

Multi-Camera Catheter Tracker
Sep 2024 - Present
Five-camera 3D tracking system for catheter position in a surgical training platform, built at Robarts Research Institute.
Overview
Designed and built the software for a capstone project at Robarts Research Institute that tracks catheter position in 3D space using five synchronized cameras. The system serves as a training tool for surgeons, providing real-time feedback on catheter placement and movement.
The Challenge
Tracking a thin, flexible catheter across five camera viewpoints required robust multi-view calibration and real-time triangulation, all while keeping latency low enough for interactive surgical training.
The Solution
Developed the full software pipeline: intrinsic and extrinsic camera calibration, ArUco tag-based coordinate alignment, YOLO-based catheter detection, and multi-view triangulation to resolve 3D position. Built a real-time Three.js dashboard served via FastAPI WebSockets for live visualization.
Outcome
The system accurately tracks catheter position in real time across the full workspace, providing surgeons-in-training with immediate spatial feedback. Completed as capstone at Robarts Research Institute.

Let's build something interesting.
I'm looking for full-time roles in automation, embedded systems, machine vision, or mechatronics, based in Waterloo, Ontario. If you're working on something technically challenging or want to talk engineering, I'm always happy to connect.
