I will fix unity bugs, c errors, android builds, firebase and iap

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
