About this gig
Is a bug breaking your web app and costing you money?
Don't let a small error ruin your user experience. I am a Senior Full Stack Developer, and I specialize in fixing the "impossible" bugs that other developers can't find.
I don't just patch the code; I find the root cause and ensure it never happens again.
I Fix These Common Issues Daily:
- React.js Errors: Hydration failed, Hooks rules, State management (Redux/Context), Infinite loops.
- Next.js Issues: Build failures on Vercel/Netlify, Server Side Rendering (SSR) errors, API Routes.
- Backend/Node.js: API connection refused, Mongoose/MongoDB queries, Express middleware errors.
- Styling: Mobile responsiveness, Tailwind CSS conflicts, Broken layouts.
My Tech Stack:
- JavaScript (ES6+) & TypeScript
- React JS, Next.js, Redux Toolkit
- Node.js, Express, MongoDB, Mongoose
Why Choose Me?
- Fast Turnaround: I understand that every minute your site is down, you lose users.
- Clean Code: I write code that is easy for you to maintain later.
- Explanation: I will record a short video explaining exactly what went wrong.
️ PLEASE CONTACT ME BEFORE PLACING AN ORDER Every bug is different. Send me a screenshot of the error, and I will give you a custom quote.
