FAQ
Do you need access to my source code?
Yes, I will need access to your source code or GitHub repository to properly analyze and fix the issues. If your app has a backend (Firebase, Node.js, Laravel, etc.), I may also need limited access to those services depending on the problem.
What kind of bugs/issues can you fix?
I can fix almost all types of issues including app crashes, UI/UX bugs, API errors, Firebase issues, performance problems, state management bugs (GetX, BLoC, Provider), and backend-related issues. If you're unsure, just message me and I’ll review your problem before you place an order.
