I will fix build or debug your react nextjs or firebase app fast
Maaz A
About this gig
If your React, Nextjs, or Firebase app is broken, failing in production, or behaving unpredictably, I can help.
I am a full stack developer who works on real production applications using React, Nextjs, TypeScript, Firebase, and modern APIs. I specialize in debugging issues that are hard to trace, such as image uploads failing midway, Firebase permission errors, authentication problems, deployment issues on Vercel, or features that work locally but fail after deployment.
I do not apply random fixes. I reproduce the issue, identify the root cause, and implement a clean and reliable solution that works in your environment or staging.
What I can help you with:
React and Nextjs bug fixing
Firebase Auth, Storage, and rules issues
Image upload and API failures
Vercel deployment and environment problems
TypeScript and component logic bugs
Performance and stability improvements
You will receive a tested fix, clear communication, and production ready code.
If you are unsure what the issue is, message me first and I will review it before starting.

FAQ
Can you fix issues you did not originally build?
Yes. I frequently debug and fix existing React, Nextjs, and Firebase codebases written by other developers.
What do you need from me to start?
I usually need access to the repository, a clear description of the issue, error messages or screenshots, and relevant Firebase or hosting access if required.
What if the issue is more complex than expected?
I will first investigate and explain the root cause. If the scope is larger, I will clearly communicate options before proceeding.
Do you guarantee the fix will work?
Yes. I verify the fix in your environment or staging before delivery to ensure the issue is resolved.
Do you provide support after delivery?
Minor adjustments are covered by revisions. Ongoing changes can be handled via an additional order if needed.
