Quizz Maker App
This project is a quiz application built using Angular for the front end and Node.js middleware, which handles Firebase authentication and data management.
Once authenticated, users can create quizzes consisting of 1-10 questions, each with 1-5 possible answers. The quiz supports both single-answer and multiple-answer question types. After quiz creation, users can publish the quiz, generating a shareable permalink with a random six-character alphanumeric code. Visitors can take the quiz without authentication.
The application will feature separate client and server components. The server will expose a REST API to support multiple potential front ends. The client will be a single-page application (SPA) without server-side rendering, ensuring modularity and flexibility.

Galaxy Conquer
Galaxy Conquer is a real-time multiplayer massively multiplayer online game (MMO) focused on resource management and time optimization. Developed with Java using Android Studio for the client side and Node.js for the back end, the game allows players to compete and collaborate in a persistent, shared world.

The back end is built with Node.js, providing seamless real-time player interactions. Firebase is used for authentication and login services, offering secure and scalable user management.
Amazon Web Services (AWS) Lambda functions are integrated to handle API requests, optimize the game's scalability, and reduce latency for multiplayer actions.
