App Debugging & Performance Optimization
An app that crashes, stutters or drains battery costs you users and reviews. I take on existing Android and Flutter apps — including ones I didn't write — to find the root cause of bugs, fix them properly, and improve how the app performs and feels.
What's included
Bug fixing & crash resolution
Reproducing the problem, finding the real cause instead of patching the symptom, and confirming the fix holds.
Performance tuning
Profiling slow screens, janky scrolling, heavy startup and memory use, then fixing what the numbers point to.
UX improvements
Smoothing rough interactions, loading states and error handling so users understand what the app is doing.
Code cleanup
Untangling fragile code so future changes stop breaking unrelated features.
Tools & technologies
- Kotlin
- Java
- Jetpack Compose
- Flutter
- Dart
- Android Studio
- Firebase
- Git
Frequently asked questions
Can you fix an app you didn't build?
Yes. Most debugging work is on existing codebases. I start by reading and reproducing the issue, then explain what's wrong before changing anything.
What do you need to get started?
Access to the source code, a description of the problem, and steps to reproduce it if you have them. Crash logs from Firebase Crashlytics or the Play Console help a lot.
Do you work on both Kotlin and Flutter apps?
Yes — native Android (Kotlin or Java) and Flutter (Dart) apps.
