You will get bugs fixed and performance improved in your React, Next.js or Node.js app


Project details
Is your React, Next.js, or Node.js application breaking, slow, or full of bugs? I will fix it fast and make it production-ready.
I am a Full-Stack Developer specializing in the MERN stack and Next.js. I don’t just fix bugs — I identify the root cause and deliver clean, optimized, and scalable solutions.
What I can fix:
Frontend Issues
• React state & rendering bugs
• Next.js hydration & routing errors
• Broken UI and responsive issues
Backend Issues
• Node.js / Express API errors
• MongoDB connection and query issues
• Server crashes and logic bugs
Performance Optimization
• Faster load times
• Memory leak fixes
• Database and API optimization
Clean code, proper debugging, and long-term solutions — not quick hacks.
Send me your code, and I’ll help turn your application into a fast, stable, and production-ready product.
