FAQ
What do you need from me to get started?
I need a clear description of the issue, access to your code (GitHub, GitLab, Bitbucket, or ZIP), and the steps to reproduce the bug.
What if the issue is bigger than expected?
If the bug requires more time or is more complex, I will let you know before starting and provide a custom offer so everything is clear and fair.
Do you need access to my server or database?
Only if the issue depends on backend or environment configuration. Otherwise, code access is enough.
Can you work with private or confidential code?
Yes. I treat client code as confidential and only use it to work on the requested issue.
Can you fix bugs in other technologies besides JavaScript/React?
Yes. I specialize in JavaScript, React, HTML, CSS, and general web debugging. If your issue involves another technology, feel free to message me first.
What if you can't fix the bug?
If I determine that I cannot resolve the issue, I will explain the situation clearly before proceeding further and discuss the best next step with you.
