I will fix unity bugs, webgl build errors, and performance issues
M. Hasnain
About this gig
Is your Unity game crashing, producing build errors, running slowly, or behaving differently from what you expected?
I will diagnose and fix bugs in your existing Unity 2D, 3D, or WebGL project and provide a clear summary of what was changed.
I can help with:
- C# errors and broken gameplay logic
- UI, menu and scene-flow problems
- Scoring, timers, progression and save/load systems
- Input, audio, physics and animation-trigger issues
- REST API and backend-integration problems
- WebGL loading, memory and browser issues
- Windows, Android and WebGL build errors
- Performance, loading-time and build-size optimization
- WebGL hosting and deployment
I have three years of paid Unity delivery experience and have built, tested and released 30+ live educational games and products. My work includes browser deployment, cloud-saved progress, REST integrations and WebGL hosting through AWS, Cloudflare and Vercel.
I work only with editable Unity project source files. App-store publishing, multiplayer, VR/AR, ads and in-app purchases are not included.
Please message me before ordering.

FAQ
Do I need to contact you before ordering?
Yes. Unity issues can vary significantly in complexity. Please send the problem description, Unity version, target platform and available error information so I can confirm the scope.
What do you need to start?
I normally need the editable Unity project, steps to reproduce the issue, expected and actual behaviour, Unity version, target platform, and any relevant screenshots, recordings or console logs.
Which platforms do you support?
I can troubleshoot Unity projects targeting WebGL, Windows/PC and Android. My strongest specialization is Unity WebGL optimization, browser troubleshooting and hosting.
Can you fix a game if I only have the compiled build?
Usually not. I need the editable Unity project and source files to diagnose and implement fixes properly.
What counts as one bug?
One bug is one reproducible issue with a defined expected result. Several symptoms caused by the same root problem may count as one issue, while unrelated problems are priced separately.
Can you add a new feature?
Small changes connected to a bug may be included after review. New gameplay systems or larger features require a separate custom offer.
Can you improve my game’s performance?
Yes. I can investigate C# execution, unnecessary object creation, loading behaviour, asset usage and platform-specific problems. I will not promise an exact FPS increase before inspecting the project.
Can you deploy my WebGL build?
Yes. WebGL building and deployment can be included in the Premium package or added through a custom offer. I have deployed Unity WebGL projects using AWS, Cloudflare and Vercel.
Do you publish games on Google Play or the App Store?
No. This gig covers Unity-side troubleshooting and builds, but it does not include store submission, store-account management or approval.
Will you modify third-party plugins?
I can investigate plugin-related issues, but support depends on access to the plugin source, its licence and compatibility with the project’s Unity version.
