You will get React & Next.js Bug Fixes - Production-Ready Code in 24 Hours
Project details
Need a React or Next.js bug fixed fast without breaking the rest of your app? This project gives you a clean, production-ready fix with a clear process and communication at every step.
I specialize in debugging React and Next.js apps, fixing issues like hooks errors, hydration problems, broken routes, API/state bugs, and layout or performance problems. You’ll get root-cause diagnosis, a reliable fix, and code that’s easy to maintain and extend.
What sets this project apart is the combination of speed and quality: a structured workflow (diagnosis → fix → testing → deployment), clear explanations of what was wrong and how it was fixed, and support after delivery. If needed, I can record a short Loom video walking through the changes so your team understands the solution.
This project is ideal if you want your bug handled quickly, safely, and professionally, without guessing or refactoring your whole app.

Arefin did a good job completing the job post successfully. He was fast to answer and I could also ask for his professional help in other matters.

Arefin delivered the agreed technical scope and successfully implemented complex integrations across booking, screening, EHR, video, and AI components. He is technically skilled, structured in his approach, and capable of handling non-trivial backend and integration work. I appreciate the work put into delivering the technical foundation.

I scope the project before writing any code, and send regular updates as I go so you're not waiting for a status check. If something's going to take longer than planned, I tell you early rather than at the deadline. You get clean, documented code and support after launch.
30+ hours/week. Response time under 12 hours. Send me a message.
