LeetCode Buddy – My AI-powered Code Review Assistant

Hey Devs! 👋

https://leet-code-buddy-trial-web-page-main.vercel.app/

I recently built something I’m super excited to share with you all — LeetCode Buddy — a personal AI-powered assistant that reviews your LeetCode code submissions and gives you instant feedback! 💡

🔧 What It Does
LeetCode Buddy analyzes your submitted solutions and gives you:

✅ Suggestions for better code quality

⚡ Optimization tips to improve time and space complexity

📚 Clean feedback — just like a mentor would!

🛠️ Tech Stack
Built entirely with the MERN stack and OpenAI API:

Frontend: React.js + CSS Modules

Backend: Node.js + Express

AI: OpenAI GPT (to generate smart, human-like reviews)

Hosting: Vercel

🎯 Why I Built This
I’m an aspiring full-stack developer looking for internships, and I realized that one of the biggest challenges for LeetCode users is understanding what’s wrong with their code — not just syntax-wise, but in terms of quality, naming conventions, and logic efficiency.

So I built this tool to act like a personal AI reviewer that helps me (and hopefully others) learn faster and smarter.

It’s still in trial mode — I’d love feedback, suggestions, or even ideas for features you'd like to see!

🙌 Open to Opportunities
I’m actively seeking tech internships, where I can contribute to real-world projects and continue learning.
If you know of any openings or want to collaborate, feel free to connect or DM me! 🤝
