Allen Chang (Yu-Lun Chang)
An undergraduate living in the Republic of China, the country that is also known as Taiwan.
I'm now striving to excel in full-stack development. Additionally, I have a keen interest in IoT, AI, and cybersecurity technologies.
My hobbies include playing piano, playing badminton, listening to music, watching animes, reading light novels, and watching Virtual YouTubers streamings. I love the ACGN culture, and my favorite VTuber is Oozora Subaru from hololive.
