I will fix reactjs bugs, hooks errors, and state issues in your react app
Saif Ur Rehman
About this gig
ReactJS bugs breaking your app or blocking your launch?
I'll fix them fast and explain every change so your team understands why.
As a Senior React developer with 4+ years of production experience, I
specialize in React hooks errors, state management bugs, and component
issues that standard debugging tools miss. I fix ReactJS problems properly
not with workarounds that create new ones next week.
What I Fix:
- Hooks & State Issues
- useState and useEffect infinite loops
- useCallback, useMemo, useRef misuse
- Stale closures and dependency array bugs
- Context API and prop drilling problems
- Component & Rendering Issues
- Components not rendering or re-rendering unexpectedly
- Key prop warnings and list rendering bugs
- Conditional rendering logic errors
- React.memo and performance-related re-renders
- State Management Issues
- Redux Toolkit and Redux Saga bugs
- Zustand and Jotai state sync problems
- React Query / TanStack Query caching issues
- Form state bugs (React Hook Form, Formik)
- Styling & UI Issues
- CSS Modules, styled-components
- Tailwind CSS class conflicts in React
- Responsive layout breaks and overflow errors

FAQ
Do you need access to my codebase?
Yes, in most cases I need to see the relevant React code. You can share via GitHub private repo, ZIP file, or paste the relevant files in chat. Your code is never shared, stored, or reused. Confidentiality guaranteed.
What if you can't fix my React bug?
I'll never accept an order I'm not confident I can resolve. Message me first, if it's outside scope I'll tell you honestly and suggest where to get help, at no cost to you.
What info should I send to get started fast?
The exact error message or screenshot, what you expected vs. what's actually happening, your React version (check package.json), and the component or file where the issue occurs.
Do you work with TypeScript React projects?
Yes. TypeScript errors, type conflicts, and generics issues inside React and TSX files are fully within scope for all packages.
Can you fix Redux bugs?
Absolutely! Redux Toolkit, Redux Saga, Redux Thunk, and legacy Redux are all within my expertise. I debug reducers, middleware, selectors, and store configuration issues.
My React component is re-rendering too many times, can you help?
Yes! this is one of the most common React performance issues I fix. I diagnose unnecessary re-renders, fix dependency arrays, apply React.memo correctly, and optimize useCallback and useMemo usage.
Which package should I pick for my issue?
Message me first and describe the bug. I'll recommend the right tier honestly. I won't upsell you to a package you don't need.
What if the bug comes back after delivery?
Unlimited revisions means I'm accountable until the fix is solid. If the same ReactJS bug reappears after my fix, contact me and I'll resolve it at no extra charge.
Can you work with Create React App, Vite, or custom Webpack?
Yes. I work with all React scaffolds. CRA, Vite, Parcel, and custom Webpack configurations. Just mention your setup when you message me.
What is your React experience level?
I'm a Senior Frontend Engineer with 4+ years of professional React experience. I was promoted to Frontend Team Lead at Graana.com after just 8 months, managing an 8-member React engineering team. I've shipped React applications across AI, real estate, and enterprises.
