I will fix unity bugs and optimize your mobile game performance
Duy V
About this gig
Stuck with a Unity bug, crash or laggy mobile game? I fix it and make it run smoothly, especially on low-end Android devices.
WHAT I CAN FIX
- Crashes, null reference errors, broken game logic
- UI, input and scene loading problems
- Ads and SDK issues (LevelPlay, AdMob, AppLovin, Firebase)
- Low FPS, memory spikes, long load times, big build size
- Android build errors
HOW IT WORKS
1. Message me with your Unity version, the bug description and, if possible, a short video or error log
2. I check your project and confirm the scope and price
3. I fix and test the issue, then send you the result with a short explanation of what changed
4. Revisions until the bug is solved, within your package
GOOD TO KNOW
- Bugs must be reproducible
- I work with C# and Unity (2020 LTS and newer)
- I focus on Android. iOS-specific bugs that need a Mac and Xcode are not included
- I do not create art or design
- Please send your project by Git or a Unity package, and keep a backup
Message me before ordering so I can confirm the scope.

FAQ
What do I need to send before ordering?
Your Unity version, a short description of the bug, steps to reproduce it, and an error log or video if you have one. Access to the project (Git or a Unity package) helps me give you an accurate quote.
Which Unity versions do you support?
Unity 6000 LTS and newer. If your project uses an older version, message me first and I will tell you if I can help.
What if I have more bugs than my package includes?
Message me before ordering. I can quote a custom offer, or you can add extra bugs with the “Additional bug” extra.
Can you optimize performance for low-end Android phones?
Yes. I use the Unity Profiler to find the cause of low FPS, memory spikes and slow loading, then fix it. Standard and Premium include optimization.
Can you fix bugs on iOS?
I can fix logic and performance bugs that appear on both platforms. I cannot debug problems that need a Mac and Xcode to reproduce, and I do not publish to the App Store.
Is my code safe and private?
Yes. I only use your project to fix the issue, I do not share it, and I do not keep copies after the order is done. I recommend you keep your own backup before sending it.
