I will fix unity bugs, c errors, android builds, firebase and iap
About this gig
Is your Unity project stuck because of a bug, build error, broken system, or SDK integration?
I will investigate the issue, identify the cause and implement a proper fix in your Unity project.
I work primarily with Unity, C# and mobile/2D game projects.
I can help with:
C# errors and NullReferenceExceptions
Broken gameplay mechanics
UI and menu bugs
Save and load problems
Player data and account persistence
Firebase Authentication issues
Firebase Firestore integration
Currency, inventory and progression bugs
Unity IAP and Google Play Billing issues
Unity Ads integrations
Android build errors
Game economy and reward logic
Existing Unity systems that are not behaving correctly
I have hands-on experience building account-based game systems with Firebase, cloud player data, currencies, shops, energy systems, purchases and mobile monetization.
I do not simply hide errors or apply temporary workarounds. My goal is to understand why the issue happens and provide a maintainable solution.
For the fastest diagnosis, please provide:
Unity version
Description of the problem
Expected behavior
Current behavior
Error messages or console screenshots
Relevant scripts or project files
