Yang Linfeng is the Founder and CEO of Onion Academy. Onion Academy, formerly known as Onion Math, was established in late 2013. It is an online education company that specializes in K-12 education, aimed at promoting a balanced allocation of educational resources by using cutting-edge technologies. Onion Academy provides online classes, which allow students to learn by interacting with the system instead of real teachers. Each class consists of a 5 to 8-minute animated video to illustrate the key knowledge point or a problem-solving approach. By using this innovative teaching method, Onion Academy hopes to attract more children to enjoy learning and studying. Furthermore, the Onion Academy’s platform is entirely cloud-based. To ensure the platform is always available, Onion Academy must closely monitor detailed metrics in the application layer to detect and prevent issues. Amid school closures from the COVID-19 pandemic, more than 7 million students and 350 thousand teachers have been using the Onion Academy app to study or teach online. Yang holds a B.A. in Computer Science from Harvard.
