I will fix bugs or take over and finish your react nextjs or node web app
Jawad Hassan
About this gig
App broken, stuck or half-finished? Did your last developer disappear? I'm Jawad, a full stack developer with 4+ years shipping production web apps. I find the real cause of a problem, fix it properly, and explain what I changed.
What I can help with:
- Bugs, errors and crashes in React, Next.js or Node.js apps
- Taking over a project after a developer left, and finishing it
- Slow pages, broken builds and deployment issues
- API, database and payment (Stripe) problems
- New features added to an existing codebase
How I work:
- I review your code first and tell you honestly what's wrong and what it will take
- Clean fixes in your own GitHub repo, with notes on every change
- Clear updates with daily overlap with UK and EU hours
Please message me before ordering with a short description of the problem, so I can confirm the right package.

FAQ
What counts as one bug?
One specific problem with one root cause, like a broken form, a failing API call or a page crash. Bigger issues that touch many parts of the app fit the Feature and Fix package. Message me first and I'll confirm which package fits.
What if the problem can't be fixed within the package?
I review your code before starting and tell you honestly if the work is bigger than expected. You can then upgrade the scope or we cancel through Fiverr. You never pay for a fix I don't deliver.
My previous developer disappeared. Can you take over?
Yes. I've taken over and relaunched client projects after the original developer ghosted. I start with a code audit, tell you what's worth keeping, then fix, finish and deploy it. That's what the Project Takeover package covers.
What access do you need?
Usually a collaborator invite to your GitHub (or GitLab) repo and, if possible, a staging environment. For deployment issues I may also need hosting access, which you can grant through your provider's team or collaborator settings.
Will you explain what you changed?
Yes. Every delivery includes a short summary of what caused each problem and what I changed, plus clear commits in your repo, so you or any future developer can follow the work.
