Electrician & Mechanical Engineering Student

I’m a third-year Mechanical Engineering student at the University of Waterloo and a certified industrial/construction electrician. I got my start with Ozz Electric, working on wiring, solar and wind installs, and major builds like Brentwood Tower 3 & 4. From there, I branched out into mechanical design and software, building up about a year of hands-on experience in each area — from testing motors and VFD systems, to CAD/FEA modeling, to Python/MATLAB automation and AI tools. I’ve also worked on residential builds, picked up skills in framing and overhead service, and joined student teams like Baja SAE to keep pushing my design skills.
