Leitner System is a web-based application designed to optimize learning through the spaced repetition and self-evaluation principles of the Leitner system. It allows users to create flashcards, categorize them based on their learning progress, and engage in daily quizzes to reinforce their knowledge. This application adheres to SOLID principles, Domain-Driven Design (DDD), and Hexagonal Architecture to ensure code quality, maintainability, and extensibility.
