I will fix bugs, refactor charp code, and optimize your unity game
Artiom Calitin
About this gig
Is your Unity project crashing, lagging, or turning into "spaghetti code"? Don't let bad architecture ruin your game's potential. Whether you have a mysterious bug that won't go away, dropping frame rates, or code that is too messy to expand, I am here to help.
With experience across 20+ completed projects, I know how to navigate complex, messy codebases. I don't just patch bugs with "duct tape"I find the root cause and implement clean, modular solutions.
What I can do for your project:
- Bug Squashing: Fix compile errors, null references, physics glitches, and logical flaws.
- Code Refactoring: Rewrite messy, interconnected C# scripts into clean, decoupled, and readable code.
- Performance Optimization: Use the Unity Profiler to find memory leaks, reduce draw calls, and fix FPS drops (especially for mobile/WebGL).
- Project Rescue: Fix broken asset integrations or salvage abandoned prototypes.
My promise: I treat your code with respect. I will leave comments explaining what I fixed and why, so you can learn from the process and continue developing without fear.

I build complete games and fix broken Unity projects. I prioritize fast development cycles and clean editor workflows over overengineered computer science theory. With a portfolio of twenty finished projects, I avoid useless complexity. I use ScriptableObjects for data architecture and keep gameplay logic completely separated from UI. This means fewer bugs and a faster release for your game. Whether you need a prototype built from scratch or a structural review of a messy codebase, I deliver working solutions instead of excuses.

FAQ
Can you fix a game that someone else coded?
Absolutely. Most of my refactoring work involves cleaning up code written by other developers or bought from asset stores.
Will you need the entire project?
Yes, usually I need the full Unity project (zipped or via GitHub/GitLab) to test the fix in the actual game environment. If the issue is in a completely isolated script, just the script might be enough.
Do you sign NDAs (Non-Disclosure Agreements)?
Yes. Your game's code and ideas are 100% safe with me. I am happy to sign an NDA before you share the source code.
What if the bug is impossible to fix?
That is exactly why I ask you to message me first! I will do a quick preliminary review of your problem. If I know I cannot fix it, I will tell you honestly before you spend any money.
