FAQ
What if you can't fix the bug?
I'll let you know upfront if the issue is outside my scope before any work begins. You won't pay for something I can't deliver.
How do I share my code with you?
GitHub repo access, a zip file, or a screen share session — whatever works best for you. I work with whatever you're comfortable sharing.
What information do you need to get started?
A description of the bug, what you expected to happen, any error messages or console logs, and access to the relevant code. The more detail you give me upfront the faster I can fix it.
