Technical details
ShopComp was a collaborate effort between myself and three of my friends in a Software Engineering course at WPI. The project idea was developed by George Heineman, the professor of the course.
ShopComp is a full stack web application that uses React/NextJS on the frontend and various AWS services on the backend, namely:
- API Gateway + Lambda proxy integrations for the RESTful API
- S3 for static website hosting
- Cognito for user identity and access management
- Aurora and RDS to host the MySQL database
My main contributions had to do with user authentication. I set up an AWS Cognito User Pool to store user credentials and validate user credentials. I constructed an authorizer for the user pool and attached it to the API Gateway endpoints, ensuring our API was inaccessible to unauthorized users. Additionally, I build a login page where new users can create an account and existing users can log in with their username and password.
