FAQ
What information do you need before I place an order?
Please share the error message, a screenshot, or your GitHub repo access. If it's a live bug, a link to the page where it happens also helps. This lets me estimate the time and fix it faster.
Do you fix bugs in projects you didn't build?
Yes. I regularly fix bugs in Next.js, React, and Node.js projects built by other developers. I'll review your codebase first to understand the structure before making changes.
What if the bug is more complex than expected?
Yes. Each package includes free re-checks if the same bug reappears within the delivery
Do you provide support after the bug is fixed?
Yes. Each package includes free re-checks if the same bug reappears within the delivery period. Premium package buyers get extended support as listed in the package.
Can you fix TypeScript errors that are blocking my build?
Yes, TypeScript build errors are one of the most common issues I fix — including type mismatches, strict mode errors, and third-party package type conflicts.
Do you also fix database or API-related bugs?
Yes. I handle bugs related to Prisma, MongoDB, PostgreSQL, and API integration issues, including connection errors and broken endpoints.
