About this gig
Are bugs, slow load times, or a messy codebase holding you back?
If you have a broken UI, frustrating React state errors, or an underperforming Next.js app, you're in the right place. I diagnose, fix, and optimize React.js, Next.js, and Tailwind CSS codebases.
I don't just band-aid problems; I write clean, scalable code for long-term success.
️ What I Can Do:
- Bug Fixes: Resolve UI glitches, hook errors, API issues, and Next.js hydration bugs.
- Refactoring: Clean messy code, extract reusable components & remove unused Tailwind classes.
- Performance: Boost Lighthouse scores & implement lazy loading for speed.
- Responsive UI: Fix mobile layouts so your app looks stunning on any device.
My Tech Stack Explained:
- ️ React.js: I fix complex state issues, eliminate bad re-renders, and refactor using modern Hooks.
- Next.js: I leverage SSR/SSG for instant load times, flawless SEO, and boosted Core Web Vitals.
- Tailwind CSS: I clean up bloated utility classes to build pixel-perfect, accessible (a11y) interfaces.
Why Choose Me?
- Detailed Reports: Clear breakdown of all my fixes.
- Proven Results: Message me for case studies!
Please message me before ordering to discuss your codebase!

FAQ
What do I need to provide to start?
Repo link (GitHub/GitLab), live URL, screenshots/videos of bugs, error messages/console logs, or a brief description of issues.
What kind of projects do you work on?
React, Next.js (App Router/Pages), Tailwind CSS, plain JS/TS, Redux/Zustand, Framer Motion — anything frontend-focused. Backend fixes (Node/Express) only if minor and related.
Do you provide a report or explanation?
Yes — detailed summary of issues found, fixes applied, and suggestions (especially in Standard/Premium).
Can you handle TypeScript or complex state management?
Yes — TypeScript errors/fixes, hooks, context, Redux, Zustand, etc., are common.
Will you refactor messy/AI-generated code?
Absolutely — I clean up "vibe code", remove duplicates, improve readability, and make it production-ready.
How do you handle revisions?
Unlimited within the original scope (fixing reported bugs, minor tweaks). Major new features or scope changes may require extra time/fee.
Do you test on multiple devices/browsers?
Yes — fixes are tested across Chrome, Firefox, Safari, Edge, and mobile views (responsive checks included).
Can I get the fixed code via GitHub?
Yes — I can push changes to a branch/PR or send zipped files. Private repo access optional (extra if needed).
What if the issue is backend-related?
I focus on frontend — for full-stack issues, I can advise or fix frontend parts only (e.g., API call handling).
Can you share case studies of codebases you've fixed?
Absolutely! I regularly solve React state bugs, fix Next.js hydration errors, and clean up bloated Tailwind files. I recently helped a client boost their Lighthouse score from 45 to 90+. Message me, and I’ll gladly share before-and-after examples relevant to your project!
