This project is the Symfony backend REST API for a flashcard platform.

I started this project because I couldn’t find a flashcard app that combined both a modern, visually appealing interface and effective functionality.

My goal was to create a good-looking flashcard app that provides a streamlined user experience.

Additionally, I wanted to deepen my understanding of the algorithms that drive flashcard-based learning, particularly those focused on optimizing review timing and content retention.

While I have always worked with Symfony for both frontend and backend, I wanted to expand into using a dedicated frontend framework like Nuxt to take advantage of Vue.js, which I really enjoy working with.

This project merges these goals by offering an intuitive platform that makes studying both efficient and enjoyable.

This project is entirely built using Symfony and its ecosystem like Doctrine. It also uses Docker and Devcontainer when developing.
