Open Textbook Exchange (OTE) is a student-focused textbook marketplace website designed for Oregon Tech students. The project’s goal is to make textbooks easier to find, share, and afford by allowing students to buy, sell, rent, or trade textbooks directly with one another. Students can create listings, search available textbooks, and connect with other users. Users can create book listings that include details such as title, author, edition, condition, images, description, and exchange information. The website also supports account creation, login, public user profiles, reviews, and account reporting to help improve trust between users. The platform was built using React, TypeScript, and Tailwind CSS for the frontend, with C#/.NET, PostgreSQL, and AWS services supporting the backend. AWS is used for API routing, data storage, authentication, validation, and serving frontend build artifacts. The database runs on AWS RDS with PostgreSQL and uses Entity Framework Core to send and retrieve data.
