I will debug and fix your javascript, react or node app
Firdavs J
About this gig
Your app was working yesterday. Today it's throwing errors like it's got something to prove.
Sound familiar? You've stared at the console for an hour, Googled the error message, tried three Stack Overflow answers that "definitely fix it" (they didn't), and you're now questioning your life choices. Relax this is exactly what I do.
I'm a JavaScript/React/Node developer who actually enjoys the "why is this broken" puzzle (yes, I know how that sounds). Give me your bug, your error log, or just a vague "it's not working" and a link to your repo I'll dig in, find the root cause (not just slap a band-aid on the symptom), and hand it back working.
What I fix:
- React bugs broken state, infinite re-renders, weird UI glitches, hooks misbehaving
- Node/Express issues API errors, broken routes, server crashes, async nightmares
- JavaScript logic errors, null/undefined chaos, integration issues
- Third-party library conflicts and dependency headaches
- "It works on my machine" mysteries
Why work with me:
- I explain what was broken and why not just a silent fix, so you actually learn something
- Clear communication, no jargon-dumping, no ghosting
- I'm newer to Fiverr, which means you get founder-era attention

FAQ
What React.js and Next.js bugs do you fix?
I fix a wide range of React.js and Next.js bugs, including rendering issues, routing errors, API data fetching problems, state management bugs, hydration mismatches, and performance bottlenecks.
Do you debug Next.js SSR and SSG issues?
Absolutely. I troubleshoot Next.js server-side rendering (SSR) and static site generation (SSG) issues — including build errors, data fetching inconsistencies (getServerSideProps, getStaticProps, getStaticPaths) and render mismatches.
Can you fix React performance problems like slow rendering?
Yes — I optimize React performance by fixing unnecessary re-renders, optimizing hooks (useEffect, useMemo), splitting bundles, and improving component structure.
Can you fix Redux, Context API & React state management bugs?
Absolutely! I debug issues related to Redux, React Context API, useReducer, and any global state management bugs affecting app behavior.
What version of React and Next.js do you support?
I support all major versions of React.js (latest and older) and Next.js, including the latest Next.js 13+ app router and older page router applications.
How quickly can you fix bugs in my React or Next.js project?
I offer fast turnaround times depending on the complexity of the bug. Simple fixes can be done within hours, and more complex React/Next.js debugging can be delivered promptly after reviewing the issue.
