I will fix nextjs and nodejs bugs and deployment errors fast
Hamza Nafasat
About this gig
Need a fast Next.js bug fix or a broken deployment rescued? Your app runs fine on your machine, then crashes the second it hits Vercel, Railway, or a VPS. That is the exact problem I fix every day.
I fix Next.js and Node.js bugs, build failures, and deploy errors. I also fix React bugs and apps built on Lovable, Bolt, v0, Replit, and Cursor, since underneath they are just React, Next.js, and Supabase.
What I fix:
Next.js and Node.js runtime errors and crashes.
Vercel, Railway, and VPS deployment failures.
Build errors that only show up in production.
Broken API routes and server side errors.
Wrong environment variables and config issues.
Auth and database connection problems.
I trace the real cause from your deployed logs and build output, not from guesswork. Send me your error or logs and I will tell you honestly if I can fix it and how long it takes, before you pay anything.
Want it checked first? Message me your error and I will look before you order.

I fix Next.js and Node.js bugs and broken deployments that pass on your machine but crash on Vercel or Railway. I also fix apps built on Lovable, Bolt, v0, and Replit when the AI code breaks.
On the AI side I build RAG chatbots, AI voice agents, and OpenAI integrations for real production apps, not quick demos. My stack is Next.js, Node.js, TypeScript, and MongoDB.
I have shipped multi-tenant SaaS, voice agents, and chatbots that answer only from your own documents. I lead a small dev team and handle the harder work myself.
Tell me what you need and I will scope it honestly first.

FAQ
What do you need from me to start?
Your error or logs, and a short note on what the app should do. GitHub access speeds it up but is not always required.
My app only crashes after deploying, not locally. Can you still fix it?
Yes, that is the most common case I get. I trace it through your deployed logs and build output instead of trying to reproduce it locally.
Do you fix bugs on Vercel, Railway, and VPS setups?
Yes, all three. Each one fails differently, so I will ask which one you are on before starting.
Can you fix apps built on Lovable, Bolt, v0, or Replit?
Yes. Those tools generate React, Next.js, and Supabase code underneath, which is exactly what I work in every day.
How fast can you turn this around?
Single clear bugs are usually done within 24 hours. Bigger deployment issues with unclear causes take 2 to 3 days.
