Hardware · Electronics · Power Systems

I am a U3 Electrical Engineering student at McGill University with hands-on experience in electronic design, PCB design and embedded systems, as well as industry experience in hardware testing, power-system protection and PCB assembly/debugging. I am particularly interested in hardware and electronics and enjoy taking projects from circuit design and simulation to physical implementation. I am eager to learn, comfortable tackling unfamiliar technical challenges, and always looking for opportunities to develop new engineering skills through hands-on work.
