I will fix react, next and typescript bugs, hydration and build errors
S M Samiul
About this gig
Is a React or Next.js bug blocking your project or breaking production?
I find the root cause, fix it safely, and verify that the rest of your app still works. No random patches and no unnecessary changes to your code.
What I can fix:
- React state, hooks, useEffect and re-render issues
- Next.js hydration, SSR, routing and build errors
- TypeScript compile and type errors
- API, form and data-mapping bugs
- Authentication and protected-route issues
- Vercel and production deployment failures
- Tailwind CSS and responsive layout problems
What you get:
- A tested fix delivered as clean code
- A short explanation of what caused the bug
- Confirmation of what was tested after the fix
- A root cause report (Standard and Premium)
Why work with me:
- Real production experience with live platforms (Next.js, Node.js, FastAPI, PostgreSQL)
- Honest scope: if the issue is bigger than your package, I tell you before starting
- Fast and direct communication
Before ordering, message me the error text, a screenshot and your stack (framework version and hosting). I will confirm the right package for you.

When you hire me, you're not getting someone who
just waits for tasks.
You're getting someone who reads your brief, spots
the real problem, and builds the solution you
actually needed — not just what you asked for.
Next.js, Node.js, Python, PostgreSQL, MongoDB,
Docker, AWS, FastAPI, Playwright/Selenium, AI integrations too.
The stack is secondary. Understanding your
product comes first.
Deadlines are kept. Scope is honest.
Communication is clear.
If you want a developer who takes ownership,
I'm ready.

FAQ
Will fixing my bug risk breaking anything else in my live app?
No, I follow safe debugging practices — testing changes carefully before delivery so your production app stays stable.
Will you tell me what caused the bug, or just fix it silently?
I always explain the root cause. On Standard and Premium packages, you get a written report so your team understands why it happened.
What if my bug is more complex than expected once you start?
I'll let you know immediately and discuss the scope before continuing, so there are no surprise costs or delays.
Can you also improve performance while fixing bugs?
Yes, this is included in the Premium package, with a before/after Lighthouse score comparison so you can see the actual improvement.
Do you need access to my live server or just the code?
Either works. I can review code directly, or work with limited, safe access to your staging/production environment if needed.
Can I contact you before ordering to describe my bug?
Of course, please share details or a screen recording of the issue. I'll confirm feasibility and recommend the right package.
Do you offer ongoing bug fixing or maintenance support?
For one-time fixes, yes. For ongoing support, feel free to message me to discuss a custom arrangement.
