Acerca de este Servicio

Are you stuck with a React, Next.js, Node.js, API, or JavaScript bug?

I will help you diagnose and fix one clear issue in your existing website, dashboard, API, or web app. This gig is best for small, focused bugs with clear steps, screenshots, logs, or repository context.

I can help with:- React component and state errors- Next.js routing, build, hydration, or API route bugs- Node.js / Express API errors- JavaScript console errors- Form, dashboard, auth, data fetching, and integration issues- Small CSS or layout problems related to the bug

What you get:- Clear diagnosis of the likely cause- A focused fix or practical fix direction depending on the package- Short notes explaining what changed- Testing notes or handover notes when included- Clean communication inside Fiverr

Good fit:- One clear bug- Existing React / Next.js / Node.js project- Console error, screenshot, repo link, or reproduction steps available

Please message me before ordering if the issue is urgent, production-critical, or requires private access. I do not work outside Fiverr and I do not handle unsafe, illegal, spam, scraping abuse, account-bypass, or credential-bypass tasks.

I help clients troubleshoot small full stack issues with clear scope and practical delivery. My work focuses on React and Next.js bugs, Node.js API debugging, authentication issues, deployment troubleshooting, environment setup, and concise handover notes. I prefer fixed scope tasks with clear reproduction steps, so I can provide focused fixes and testing notes.
