Mr. Lee would describe himself as a 2-in-1 educator, a former laboratory analyst and engineer molded into an educator. He graduated with a Master's degree in Mechanical Engineering, majoring in Automotive Engineering. Before transitioning into teaching, he worked in a science lab and at a car workshop to gain a better understanding of how a car works.

He strongly believes that sharing his experiences from outside the education world provides students with insights beyond what's found in textbooks, especially when it comes to applying knowledge in daily life. Additionally, he always emphasizes the importance of a "true understanding" of how mathematics and science work during his lessons.

Apart from teaching during the school week, he becomes a weekend warrior in the car modification field. Calibrating a car engine, designing/wiring car electronic systems, and even working as a race/strategy engineer in race events are some of the things he does on weekends.
