I will fix your javascript, typescript, react, nodejs, fastapi code

I will professionally debug and fix bugs in your JavaScript, TypeScript, React, Node.js, or FastAPI code.

If your app is throwing errors, behaving incorrectly, crashing, or not working as expected, I will identify the root cause and fix it properly, not just apply a temporary workaround.

What I can help you with:

• JavaScript / TypeScript bugs
• React errors (hooks, state, props, rendering issues)
• Node.js backend bugs
• FastAPI route, validation, and API issues
• Async / promise problems
• Logic bugs and broken features
• Console errors & runtime errors
• Integration issues between frontend & backend

What you get:

• Careful bug investigation
• Clean and reliable fixes
• Optional documentation fixes
• Optional detailed code comments
• Clear explanation of what was wrong and how it was fixed

Important:

Please message me before ordering with:

• A short description of the problem
• Error messages or screenshots
• Code snippet or repository access

This helps avoid misunderstandings and ensures fast delivery.

• If you need a quick fix or deep debugging, youre in the right place.
