I've been passionate about programming since elementary school. I used the internet to learn and even built my own website by sixth grade. This passion led me to compete in the National Science Olympiad during high school, where I focused on complex algorithms and won third place in a national coding competition. This achievement helped me get into one of Indonesia's top computer engineering universities, where I worked on a project in image processing. I also gained valuable experience through an internship at NTUST in Taiwan. After graduating, I earned a scholarship for a master's program in computer vision with a renowned professor, and I successfully obtained my master's degree.
