	Component	Details
⚙️	Architecture	Microservices architecture with a backend and frontend
🔌	Integrations	Uses Spring Framework for backend services Nuxt.js for frontend with i18n, pinia, and eslint integration Uses bootstrap 5 for styling
🧩	Modularity	Backend is modularized into different services (e.g., user-service) Frontend components are built per-file, dynamically addressed to build the DOM
⚡️	Performance	Uses Caffeine for caching, improves performance for querying JWTs, and Redis for distributed caching
🛡️	Security	Includes security libraries like BouncyCastle and NimbusDS Passwords are hashed with Argon2id, top choice for passwords JWT tokens are signed using ES256, the better option would be EdDSA over ECDSA but tech stack lacks support
📦	Dependencies	Manages dependencies using pnpm for frontend and Gradle for backend Includes a variety of libraries such as Spring Framework, Nuxt.js, Pinia, and Bootstrap
🚀	Scalability	Built on microservices architecture to allow horizontal scaling of individual services when demand rises Containerized and can be orchestrated by k8s for auto scaling Uses UUID v7 to allow distributed systems decoupling while remaining easy to index
