I will fix react and node js bugs in your web application
Josue Varela
Informazioni su questo servizio
Is your React or Node.js web application broken, crashing, or underperforming?
When your app is down or throwing errors, you are losing users and money. You don't need a beginner to guess the problem; you need an expert to diagnose and resolve it quickly.
I specialize in rescuing codebases. Whether it is a frontend state management issue in React, a broken REST API in Node.js, or a complex PostgreSQL database error, I will find the root cause and deliver a clean, permanent fix.
What I can fix for you:
- React Issues: Hooks, state errors, UI/UX glitches, routing problems, and responsive design fixes.
- Node.js & Backend: API endpoint failures, middleware errors, authentication issues, and server crashes.
- Database: PostgreSQL queries, connection timeouts, and data rendering issues.
Why me?
- Fast Diagnostics: I read and understand complex codebases quickly.
- Clean Code: I don't use "band-aid" solutions. I fix the core logic.
️ IMPORTANT: Please send me a message with a description of the bug or an error screenshot BEFORE ordering so I can evaluate the complexity.

FAQ
Question 1: What do you need from me to start fixing the bug?
Answer: I need a clear description of how to reproduce the error, access to your source code repository (GitHub, GitLab, etc.), and any necessary environment variables.
Question 2: Do you fix bugs in WordPress or Shopify?
Answer: No. I specialize exclusively in custom web applications built with modern JavaScript frameworks (React and Node.js).
Question 3: What if my bug is extremely complex and requires a lot of code refactoring?
Answer: If after reviewing your code I determine the issue requires deep architectural changes or full component refactoring, I will provide you with a custom quote tailored to the scope of work.
