Infinity Simon

My first Agile project during university where I served as team leader, designer, and frontend developer. We took the classic Simon Says memory game and evolved it into a competitive multiplayer web application with an enhanced game mode.

My Role

• Team Leader: Coordinated the team, managed sprints, and facilitated Agile ceremonies.
• Designer: Created UI/UX designs and wireframes for the application.
• Frontend Developer: Implemented the React-based frontend with TypeScript and Tailwind CSS.

Features

• ✅ Single-player and multiplayer competitive modes.
• ✅ Enhanced game mode with additional input types beyond the classic four buttons.
• ✅ User authentication with email verification and password recovery.
• ✅ Player profiles with avatars and detailed statistics.
• ✅ Seed-based match system ensuring fair competition.
• ✅ Fully responsive design.
• ✅ Guest mode for trying the game without registration.

Tech Stack

Frontend

• React: React 19 with TypeScript for the client application.
• Tailwind CSS: For styling and responsive design.

Backend

• Node.js & Express: REST API handling user management, seed generation, and match coordination.
• Prisma ORM: Database schema management with type-safe queries.
• SQLite: Storing user data, match results, and statistics.

Architecture & Deployment

The backend follows clean architecture principles with separate presentation, business logic, and persistence layers. The multiplayer system uses seed-based generation: the server creates a unique seed for each match, ensuring all players experience identical sequences while keeping game logic client-side for responsive gameplay.

• Docker: Containerized deployment for both frontend and backend.
• Jest: Testing framework for backend services.
• Swagger/OpenAPI: API documentation.

What I Learned

• Implementing user authentication with email verification and password recovery flows.
• Working collaboratively in a team environment with code reviews and version control.
• Agile methodology with sprints, daily standups, and iterative development.
• Using Kanban boards (Trello) for task management and progress tracking.
• Git workflows with pull requests, code reviews, and branch management.
• Writing comprehensive documentation including functional specifications, requirement specifications, and system design documents.
