FAQ
How do I know if you can fix my bug?
Just send me a message describing the issue, share a screenshot of the error, and I'll review it and tell you honestly whether I can help — before you spend a single dollar.
What information do I need to share with you?
Ideally: a description of the problem, the error message or screenshot, and access to the relevant code (GitHub link, zip file, or code snippets). The more context you provide, the faster I can fix it.
Will you create new bugs while fixing mine?
No. Every fix is tested carefully before delivery. I identify the root cause and apply a targeted solution so the rest of your codebase stays untouched.
What if my issue isn't fixed after delivery?
I offer revisions. If the problem persists or comes back, message me and I'll look into it. I don't consider a job done until your app is actually working.
Can you fix bugs in a project you didn't build?
Yes, absolutely. Most of my work involves debugging other developers' code. I'm experienced with jumping into unfamiliar codebases and diagnosing issues quickly.
Do you handle urgent or production-down issues?
Yes. If your live site is broken and you need fast help, message me and mention it's urgent. I prioritize production issues whenever possible.
What if my bug is very complex?
Message me first. Complex bugs may need a custom quote. I've tackled issues that other developers couldn't solve — don't give up before reaching out.
