Software Engineer · Full-Stack & AI Systems
Final-year Computer Engineering student at UCLM with hands-on experience building full-stack applications, AI-powered tools, and data-driven systems. Focused on writing clean, tested, and deployable software.
Production-ready web platform to play board games online in real time. Includes three fully implemented games (Última Carta, Connect 4, Checkers), AI opponents, and a complete authentication system. Deployed on Google Cloud Run.
Tech Stack: Node.js · Express · Socket.io · MongoDB · React 19 · Vite · Passport.js · Google OAuth 2.0 · Playwright · Vitest
Key Features:
- Real-time multiplayer gameplay via WebSocket (Socket.io)
- Local and Google authentication (OAuth 2.0 + One-Tap), email verification and password reset
- AI opponents with minimax + alpha-beta pruning (Connect 4 & Checkers)
- 255 automated tests (202 server + 53 client), including E2E with Playwright
- Deployed and accessible on Google Cloud Run
What I did:
- Designed and implemented the full-stack architecture (client, server, WebSocket layer)
- Built the authentication system (local + Google OAuth) and user management
- Developed AI game engines and real-time game logic for three different games
- Set up the testing suite (unit, integration and E2E) and CI/CD pipeline
- Deployed the application to Google Cloud Run
