ABOUT ME
Hi, I'm Polezero.
I'm an engineer working on vehicle electrification at a major automotive manufacturer. Here I teach embedded systems, with a particular interest in motor control.
Teaching in Korea
I also teach embedded systems and motor control in Korea through my Korean-language courses on Inflearn.

Why I teach
In college, I took courses that taught me to blink an LED, generate PWM, and handle an interrupt. Putting those pieces together was harder. The advice was usually to build a project, but it was rarely clear where to begin.
I started making lessons to help with that step. I want you to understand how a circuit becomes a working system, and to have enough grounding to make your own design decisions.
The decisions behind the design
My work has taught me to take verification seriously. A controller that runs on the bench still has to behave consistently in a vehicle.
That perspective shapes my teaching. I explain why I chose a component, where I placed a current sensor, and how the firmware uses the measurement. The reasoning matters as much as the finished board.
