FAQ
Do you need access to my entire GitHub repository?
Not necessarily. You can share specific code snippets or invite me as a collaborator to the specific repository. For small UI fixes, a ZIP file of the source code also works.
What if you are unable to fix the bug?
If I cannot resolve the technical issue after investigation, I offer a 100% refund. Your satisfaction and project success are my top priorities.
Do you offer long-term maintenance?
Yes! If you need someone to monitor your app and fix bugs on a monthly basis, we can discuss a custom management package.
Can you fix bugs in custom MERN stack applications?
Yes, I am highly proficient in the MERN stack and can debug issues across the frontend, backend, and database layers.
