I will fix react, next js and node js bugs and errors fast
Fahad Khan
About this gig
Need to fix bugs or errors in your React, Next.js, or Node.js app?
I'm a full-stack developer with experience building and shipping apps for real clients. I fix frontend, backend, API, and database issues cleanly and explain exactly what was wrong.
What I fix:
- React, Next.js, JavaScript & CSS broken UI, rendering, console errors
- Node.js, Express & REST API errors, server crashes
- Database issues MongoDB, PostgreSQL (Drizzle/Prisma), MySQL
- Integrations Stripe, Firebase, auth, third-party APIs
- Build, deployment & performance problems
How I work:
I find the root cause using dev tools and logs, apply a clean fix, and send a short explanation. I use safe practices on live apps so existing features keep working.
Why me:
- Experienced shipping real client apps
- Fast, honest timelines
- Plain-language explanations
- I fix the real cause, not just patch it
I specialize in MERN but work across the full stack Next.js, Node.js, and both SQL and NoSQL databases.
Message me before ordering with your bug so I can confirm scope and timeline.

I’m a full-stack developer primarily working with the MERN stack to build fast, scalable SaaS applications.
I focus on turning ideas into real, usable products, from MVPs to full production-ready web apps. My approach is clean architecture, practical engineering, and building features that actually ship and perform.
With a strong interest in AI-powered development workflows and modern product engineering, I help clients build software ready for rapid iteration and today’s fast-moving development landscape.
If you need someone to turn your idea into a working product, I can help.

FAQ

I'll review it first and tell you honestly before starting. If it's bigger than expected, we'll agree on scope and timeline with a custom offer, no surprise charges.
Will you break my existing app while fixing it?
No. I use safe debugging practices on live and production apps, and test changes before delivery so your existing features keep working.
Do you also build full apps, not just fix them?
Yes.I specialize in MERN (React, Node, MongoDB) and build full-stack, including Next.js and PostgreSQL with Drizzle ORM. Message me and I'll send a custom offer.
Which databases and tools do you work with?
Both SQL and NoSQL, MongoDB, PostgreSQL (Drizzle/Prisma), and MySQL. I also handle Stripe, Firebase, authentication, and third-party API integrations.
