FAQ
What do you need from me to get started?
I’ll need a clear description of the issue, your project files or repository access (GitHub/ZIP), and any steps to reproduce the bug. If backend access is involved, I may also need temporary credentials.
What technologies do you work with?
I work with HTML, CSS, JavaScript, React, Next.js, Vue, Node.js, Express, Laravel, PHP, MongoDB, and MySQL. If you have another stack, feel free to message me first.
Can you fix bugs in both frontend and backend?
Yes! I’m a full-stack developer. I can fix issues across both frontend (UI, CSS, JavaScript, etc.) and backend (API, database, server logic, etc.).
I’m not sure what’s causing the bug. Can you investigate it?
Absolutely! If you’re unsure, just describe the issue and I’ll investigate it for you before jumping into the fix. I’ll give you a quick diagnosis and suggest the best solution.
What if the issue turns out to be bigger than expected?
If the issue is larger than your selected package, I’ll inform you immediately and offer a custom offer or suggest the appropriate package upgrade, with no hidden charges or surprises.
Can you also optimize or refactor my code after fixing the bugs?
Yes, that’s included in the Premium package. I’ll clean up your code, improve performance, and offer recommendations for long-term maintainability.
Do you offer long-term support or maintenance?
Yes, if you're looking for ongoing support, we can set up a custom offer or a monthly maintenance plan. Feel free to contact me to discuss it.
