Good day, everyone! Thamarai is my name (Tom). Since August 2019, I've been pursuing a Ph.D. in Mechanical Engineering at National Chung Hsing University in Taichung. I provide math instruction for both primary and secondary school students. I've been teaching for 5 years and am a specialist in working with young children. As per your convenience, it is available both online and offline (in your location). Thank you very much! Have a wonderful day!
