Acerca de este Servicio
Stop wasting hours on stubborn bugs. Let an Open Source Engineer handle it.
Is a broken feature or a cryptic error stalling your project? I specialize in rapid troubleshooting and clean feature implementation for NextJS and React applications. As an active contributor to major open-source projects like Chromium and Joplin, I apply elite engineering standards to every fix.
Issues I Resolve Daily:
- NextJS Errors: Hydration mismatches, 404/500 errors, and build failures.
- React Logic: Debugging complex Hooks, Context API, Redux, or Zustand.
- API & Database: Troubleshooting Axios, Fetch, MongoDB, or Appwrite.
- UI & Styling: Responsive design repairs and pixel-perfect Tailwind CSS fixes.
- TypeScript: Resolving "any" types and complex interface conflicts.
Why hire a specialized engineer?
- Production Standards: Clean, maintainable, and type-safe code only.
- Rapid Turnaround: Most bugs diagnosed and fixed within 12-24 hours.
- Open Source Expertise: Leveraging the same rigor used in world-class software.
Stop the frustration and get your project back on track today.

I build high-performance, production-ready web applications that help businesses grow. Whether you need a modern website, SaaS dashboard, or custom web application, I focus on clean design, secure architecture, and scalable code.
I specialize in Next.js, React, TypeScript, Node.js, and MongoDB, with experience building payments, authentication, real-time features, and APIs. I’ve also made 15+ merged open-source contributions to Chromium, Joplin, and Jenkins. My goal is to turn your ideas into fast, reliable, and easy-to-maintain products.

FAQ
What do you need to start the fix?
To begin immediately, I need three things: 1) A brief description of the issue. 2) A screenshot or text of the error log from your console/terminal. 3) Access to your repository (GitHub invite or a ZIP file of the source code).
Can you fix Next.js hydration or build errors?
Yes. These are common issues in Next.js 14 and 15. I specialize in resolving hydration mismatches, server-side rendering (SSR) conflicts, and Vercel deployment failures by ensuring your components and data-fetching logic are correctly structured.
Do you work with TypeScript and modern State Management?
Absolutely. I prefer working with TypeScript to ensure type safety. I can debug issues within Redux Toolkit, Zustand, Context API, and TanStack Query (React Query) to ensure your application state is predictable and bug-free.
What if the bug is larger than the "Basic" package?
If the issue requires a deep architectural overhaul or involves multiple complex files, I will provide a detailed diagnostic report and a custom offer. Transparency is key—I will always explain the "why" behind the fix.
Is my code secure with you?
Yes. As an Open Source contributor, I follow strict security protocols. I will never share your code, and I ensure that environment variables and sensitive API keys are handled securely during the debugging process.
