Hey devs 👋
I’m Parag Bhosale, a React and Next.js developer who loves building things that make coding fun.
Over the past few weeks, I’ve been working on something exciting — a platform called Dev Battle, where developers can compete in real-time coding challenges, fix bugs, and climb the leaderboard 🏆
🎮 What Is Dev Battle?
Dev Battle is a real-time coding challenge app inspired by platforms like CodeWars — but with a twist.
You can:
- 👥 Log in using Google or email
- ⚔️ Challenge your friends to fix coding bugs or answer quizzes
- 🧠 Solve daily challenges and quizzes
- 💬 Chat live with other players
- 🏅 Unlock achievements as you play
I wanted to make coding social, competitive, and fun — not just about solving problems alone.
🧑💻 Tech Stack
Here’s what powers Dev Battle:
- ⚡ Next.js 15 – frontend & routing
- 🔥 Firebase – auth, Firestore database, and real-time updates
- 💬 Socket.io – real-time communication between players
- 🎨 Tailwind CSS – modern, responsive UI
- ☁️ Vercel – for smooth deployment
⚙️ How It Works
When two users start a challenge:
- The system picks a bug or quiz from Firestore.
- Both players fix it within a time limit.
- Scores are updated in real-time on the leaderboard.
It’s like a mini coding battle arena, where logic and speed both matter ⚡
🚀 Live Demo & Code

⚠️ The app is still in its beta phase — there might be small bugs.
Please report them if you find any! I’m finalizing the app this Sunday 🙌
🎯 What’s Next
- 👥 1v1 real-time bug-fixing arena
- 🧩 Code snippets & discussion section
- 🧑🤝🧑 Friend system improvements
- 📈 Weekly leaderboards and achievements
🧠 Why I Built It
I wanted to level up my React + Firebase skills and build something that feels like a real project, not just a tutorial.
Also — let’s be honest — coding is way more fun when you can battle your friends 😄
I’m currently open to new opportunities as a React / Next.js developer, and this project showcases what I love doing most:
Building interactive, real-time, and user-focused web experiences.
Let’s make coding fun again 💻⚔️
