My name is Wasim Khan, an experienced Native Android Developer with 4+ years of expertise in building scalable and high-performance mobile applications. I specialize in Kotlin, Java, Jetpack Compose, and XML, following MVVM and Clean Architecture principles.

Veelgestelde vragen
1. What do you need to start fixing the bug?
To get started, I need access to the source code (or the specific file causing the issue) and a detailed description of the bug. If available, please provide Logcat logs, Firebase Crashlytics reports, or a screen recording showing how the crash occurs.
2. Can you fix ANR (Application Not Responding) issues?
Yes, resolving ANR is one of my specialties. I analyze the main thread to identify blocking operations and move them to background threads using Kotlin Coroutines or WorkManager to ensure a smooth user experience.
3. Will you provide the fixed source code?
Absolutely. Once the android app bug fix is complete and tested, I will deliver the updated source code with comments explaining the changes made. I ensure the code remains clean and follows MVVM/Clean Architecture standards.
4. Do you offer a guarantee that the crash won't return?
I provide a 100% satisfaction guarantee. I test the fix against the specific scenarios that caused the fix crashes in the first place. If the same bug reappears within 7 days of delivery, I will fix it again for free.
5. Can you help with Play Store rejection issues?
Yes. If your app was rejected due to technical bugs, crashes, or policy violations related to app performance, I can diagnose the reason, apply the necessary app optimization, and help you get it ready for a successful resubmission.
6. Is my source code safe with you?
Security and privacy are my top priorities. Your source code will be used strictly for the purpose of the bug fixing task and will not be shared with any third party. I am happy to sign an NDA if required.
