I will fix your mern stack mongodb, express, react, nodejs application bug


About this gig
Is a stubborn bug breaking your application or stopping your deployment? Don't let code errors halt your business. As a full-stack developer specialising in the Node.js ecosystem, I will trace, isolate, and repair your application crashes efficiently.
The JavaScript and TypeScript landscape has shifted, and modern apps present unique configuration bottlenecks. Whether it is an issue with server-side rendering or complex dependency networks, I have the experience to get your code working flawlessly.
What I Fix:
- Frontend: Next.js App Router hydration errors, React state management mismatches (Redux Toolkit/Zustand), and Tailwind CSS layouts.
- Backend: NestJS dependency injection issues, Express async middleware errors, and TypeScript compilation crashes.
- Databases: MongoDB connection drops, indexing bottlenecks, and Mongoose validation failures.
- Production: Deployment crashes on Vercel, Heroku, AWS, or Render.
Why Choose My Service?
- Professional, clean refactoring- never messy patch-ups.
- Transparent communication via clean, commented code explanations.
- Fast turnaround to bring your system back online instantly.
