I will fix react and next js bugs and frontend errors fast
Himanshu Singla
Acerca de este Servicio
Stuck on a React or Next.js bug that's already eaten your day?
I'm a frontend engineer with 3+ years shipping production React and Next.js apps at funded startups. I find the actual cause, fix it properly, and explain what happened.
WHAT I FIX
- React state, re-render and hook issues useEffect loops, stale state
- Next.js hydration errors, routing, SSR/ISR and build failures
- Layout and responsiveness bugs CSS, Tailwind, flexbox, grid
- API and data-fetching errors, CORS, async race conditions
- TypeScript type errors and console warnings
- Broken deploys on Vercel and Netlify
WHAT YOU GET
- A working fix as a clean commit or a diff you can review
- A short written explanation of the root cause
- How to avoid the same bug next time
STACK
React, Next.js, TypeScript, JavaScript, Redux Toolkit, React Query, Tailwind, MUI, shadcn/ui, Node.js, Express.
Most single bugs are delivered the same day.
Message me first with the error text, a screenshot, or a repo link. I'll tell you honestly whether it's a 20-minute fix or a bigger structural problem and I'll say so if it isn't worth paying me for.

FAQ
What if I have more than the package covers?
Message me first. I'll quote a custom offer rather than let you overpay or under-buy.
Will you explain what caused it?
Yes, every delivery includes a plain-English root-cause note.
Do you need repo access?
Ideally. A GitHub invite, a ZIP, or a CodeSandbox all work.
Can you work on Next.js App Router / TypeScript / React Native?
Yes to all three.
What if you can't fix it?
I'll tell you within a few hours and cancel before the clock runs, so you lose nothing.
