FAQ
Do I need to share my full project code with you?
Not always. You can share only the specific files or modules where the issue occurs. If needed, I’ll guide you on how to safely share your project.
Can you fix both Java and Kotlin projects?
Yes ✔ I fix bugs in Java, Kotlin, or hybrid Android projects.
Do you fix backend or API issues too?
Yes. I can resolve API, Firebase, and database-related bugs as long as you provide access/credentials.
Will you also explain what caused the bug?
Absolutely. I don’t just fix errors — I also explain the issue so you understand how to avoid it in the future.
Do you work on university/college assignments or console programs?
Yes, I can fix Java/Kotlin console programs and assignments too (not just Android apps).
What if my app has multiple bugs?
Please contact me before ordering. I’ll review your project and suggest the right package (Basic, Standard, or Premium).
Do you guarantee bug resolution?
Yes ✔ I offer a 100% bug resolution guarantee or I’ll refund if I can’t solve it.
