Excited to share my latest project — BINGO: Real-Time Multiplayer Online Game
I built a complete multiplayer BINGO game with a strong focus on real-time gameplay, responsive UI, smooth animations, and user-friendly multiplayer interactions.
The game allows users to create private rooms, invite online players, join using a Room ID and password, set up their own Bingo board, and play against friends in real time.
Key features include:
Real-time multiplayer using Socket.IO
(http://Socket.IO)Secure Login & Registration
Private room creation and joining
Online player invitations with Accept / Reject
Host-controlled match start
2–5 player support with dynamic board sizes
Manual and random Bingo number setup
Duplicate and invalid-number validation
Keyboard arrow navigation
Real-time number marking across players
Win / Loss / Draw detection
Animated BINGO winner celebration
Rematch and Exit options
Weekly Top 10 leaderboard
Winner = 100 points, Draw/Loss = 0 points
MongoDB-based user data and authentication
Fully responsive design for mobile, tablet, laptop, and desktop
Performance-optimized animations for smooth gameplay
🛠️ Tech Stack:
React.js • Vite • JavaScript • Node.js • Express.js • Socket.IO (http://Socket.IO) • MongoDB • JWT • bcrypt • Framer Motion • CSS
Building this project helped me understand real-time multiplayer architecture, WebSocket communication, authentication, server-side game validation, state synchronization, and responsive game UI design much better.
I’m continuing to improve the project and explore more real-time web application concepts.
Feedback and suggestions are always welcome! 🎮✨

I’m excited to share NeuroChat, a full-stack AI chatbot platform that I designed, developed, tested, and successfully deployed on Render.
• 🤖 Built a multi-provider AI architecture using Gemini, OpenRouter, and Groq with automatic fallback, reducing dependency on a single AI provider.
• 🎙️ Supports voice messaging, allowing users to speak their queries and interact with the chatbot naturally.
• 🌍 Supports multiple languages, making NeuroChat more accessible for users from different linguistic backgrounds.
• 🌐 Users can ask about recent and current updates, with Google Search grounding helping provide up-to-date information and relevant sources.
• 💬 Includes real-time streaming responses, conversation memory, Markdown/code support, rate limiting, and secure multi-user authentication using Firebase Authentication and Firestore.
• 🆓 Designed to be free to use within the available free-tier limits, allowing users to explore AI-powered conversations without requiring a paid subscription.
• 🛠️ Tech Stack: Next.js, TypeScript, Tailwind CSS, FastAPI, Python, Firebase, Firestore, Gemini, OpenRouter & Groq.
🌐 NeuroChat is now live on Render!
This project helped me gain practical experience in AI integration, multi-model orchestration, voice interaction, multilingual AI, real-time systems, authentication, backend security, and production-oriented full-stack development.
