Over deze dienst
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.
