About this gig
Is your React, Next.js, or Node.js application broken, buggy, or falling behind modern standards?
I can fix it or rebuild it from the ground up.
I'm a full-stack developer specializing in React.js, Next.js, Node.js, TypeScript, JavaScript, HTML/CSS, and Tailwind CSS. Whether you're dealing with a single frustrating bug or an entire codebase that needs professional restructuring, I bring both problem-solving precision and clean architecture to every project.
What I fix:
- Runtime errors, console warnings, and application crashes
- Component rendering, re-render, and state management issues
- Broken layouts, responsiveness, and styling inconsistencies
- Node.js/Express API errors and server-side bugs
- Database connection, query, and data integrity issues
- Authentication, routing, and API integration failures
- Build, deployment, and TypeScript type errors
- Performance bottlenecks across frontend and backend
What I rebuild:
- Legacy JavaScript codebases migrated to clean, type-safe TypeScript
- Outdated React applications upgraded to modern Next.js architecture
- Messy or unscalable Node.js backends restructured for maintainability
- Cluttered UI redesigned with Tailwind CSS
- Full-stack applications re

FAQ
What information do you need from me to get started?
Please share your code repository (GitHub/GitLab link or ZIP file), the error message or console log, and a brief description of what's not working. A screen recording of the issue is also very helpful.
Can you fix bugs without seeing my full codebase?
For small, isolated bugs, sometimes yes — but for most issues, I'll need access to the relevant code to properly diagnose the root cause rather than guessing.
Do you work with both frontend and backend issues?
Yes. I handle React.js and Next.js frontend bugs as well as Node.js/Express backend and API issues, including database connection problems.
What's the difference between "bug fix" and "rebuild"?
A bug fix addresses specific broken features or errors in your existing code. A rebuild means restructuring, refactoring, or migrating your codebase (e.g., converting JavaScript to TypeScript, or upgrading React to Next.js) for better performance and maintainability.
Will I get a report of what was fixed or changed?
Yes, I provide a summary of the issues found, what was fixed, and any recommendations for future improvements.
Do you sign NDAs or handle private/proprietary code?
Yes, I'm happy to sign an NDA if required and treat all client code and data with full confidentiality.
What if the bug is more complex than expected once you start?
I'll message you immediately to discuss the situation. Depending on the complexity, we can adjust the package or scope before continuing — no surprise charges.
Can you also add new features while fixing bugs?
Small feature additions can sometimes be included depending on scope — message me with details, and I'll let you know if it fits within the package or needs a custom quote.
Do you provide ongoing support after delivery?
Basic support for the delivered fix is included. For ongoing maintenance or future updates, we can discuss a separate arrangement.
What tech stack/tools do you use?
React.js, Next.js, Node.js, Express, TypeScript, JavaScript, Tailwind CSS, and REST APIs. I also work with common databases like MongoDB, MySQL, and PostgreSQL.
