FAQ
What do you need from me to get started?
Share your code (or a GitHub link), describe the issue, and include any error messages or screenshots. The more context, the faster I can fix it.
What if you can't fix my issue?
I'll let you know before you order if the problem is outside my scope. I don't take jobs I can't complete.
Do you work on large codebases?
Yes. For larger projects, message me first so I can review the scope and recommend the right package.
Will you explain what you changed ?
Always. Every delivery includes a clear summary of what was broken, why, and exactly what I changed to fix it.
