In my junior year of high school at the SMIC Private School in Shanghai, I worked with 2 of my classmates and built a full blown WeChat Mini Program for students and parents to buy and sell school textbooks more effectively. In the mini program, you could see what others have listed for sale and contact the seller with a push of a button. You could also upload pictures of your own books for sale on the platform. We even built a messaging system inside our mini program using WebSockets. As of September 2022, we have attracted more than 1900 users and have more than 1100 book listings of which more than 600 are successful transactions. One of the things that I am most proud of about this project is saving students who needed a textbook really urgenty for class but couldn’t find it anywhere else.
