Many students in MSU are engaged in either making and helping a small business or purchasing a preloved item for sustainability. Due to the rapid growth of the internet, now numerous people are fulfilling their needs to shop online. In MSU, there is no platform to provide a place to shop among MSUrians. That said, there are some discussions that sometimes the sales promotion cannot get through or cannot be delivered effectively to the target audience or customers. There is no specific platform to combine both passion and creativity, focusing on the entrepreneur field. Therefore, in this study, the developer tries to build an e-marketplace android mobile application named Red. The methodology used to develop the application is SDLC. Its primary purpose is to allow, not only students but staff in MSU too can shop and support each other. The application requires their matric number to sign up. So only MSUrians can access the application.
