Users can register accounts and log in to PaddleUp, enabling them to play matches against each other using socket technology. Players can view their scores, match history, and a leaderboard featuring the top players. Additionally, users can favorite other players ("add a friend") on the leaderboard to track their performance in the statistics.

This project was built with React, including a vanilla JavaScript component for the playable match functionality. We used PicoCSS as the CSS library, and stateless components were documented with Storybook.

The back-end / API was developed with Express. We used MongoDB for the database, and Socket.io for socket implementation. The API is documented using Swagger.
