Backend API for Authentication System with Node.js and Fastify

Developed a high-performance backend API for an authentication system using Node.js and the Fastify framework. The API handles user registration, login, and firebase token-based authentication (JWT). Fastify was chosen for its low overhead and high scalability, providing an efficient way to manage multiple authentication requests. Integrated secure password hashing, user validation, and session management to ensure robust security practices. This solution streamlined user authentication and authorization processes, while maintaining high responsiveness and reliability under heavy traffic.
