I will fix bugs and improve performance in your react website
Agustin P
About this gig
Is your React app throwing errors, rendering the wrong data, or loading too slowly? I find the root cause and fix it. I don't patch over it.
WHAT I FIX
- Runtime errors, blank screens and broken builds
- State and re-render issues (useEffect loops, stale state)
- API integration problems and CORS errors
- Slow load times, heavy bundles, unoptimized images
- Responsive and layout bugs across devices
- Styling issues in Tailwind CSS and plain CSS
HOW I WORK
1. You send the repo and how to reproduce the issue
2. I reproduce it and find the actual cause
3. I fix it, test it, and explain what was wrong
You get clean, commented code and a short written summary, so you understand the fix instead of just receiving it.
I work with React, JavaScript, TypeScript, Astro, Tailwind CSS, Node.js and REST APIs.
Not sure if your issue fits? Message me first with a short description. I'll tell you honestly whether I can help and which package you need. If I can't help, I'll say that too.

FAQ
What do you need from me to start?
Access to the code (GitHub repo or a ZIP file), the live URL if there is one, and clear steps to reproduce the issue. The more detail you give me, the faster the fix.
Do you offer support after delivery?
Yes. If the same bug comes back within 14 days of delivery, I'll fix it at no extra cost.
What if you can't fix it?
If I can't solve the issue, I'll tell you as soon as I know and cancel the order. You won't pay for a fix that doesn't work.
Will you break something else while fixing my bug?
I work on a separate branch and test the affected areas before delivering. You review the changes before merging anything.
Can you work on Next.js, Vue or Angular projects?
My focus is React, Astro and vanilla JavaScript. Message me with your stack before ordering and I'll tell you honestly if I can help.
