Description

Doriann Xavier, Unity developer specializing in C# debugging and bug fixing for video game projects. Based in Bordeaux.

Do you have a blocking bug in your Unity project? I quickly fix your gameplay, performance, UI, and physics issues. Whether your game crashes on build, your collisions aren't working correctly, or you have memory leaks that slow everything down: I identify the cause and deliver a clean fix within 48 to 72 hours.

What sets me apart: I am trained in video game development, which allows me to quickly understand your codebase and propose solutions adapted to the gameplay context. I am responsive and work fast. Examples of bugs I regularly handle: build issues that work in the editor but crash on Android/iOS/WebGL, objects passing through walls at high speed, progressive memory leaks, UI bugs on different resolutions, raycast or collision detection problems, state corruption in game managers.

Deliverables: corrected and tested code, documentation of changes, pull request or patch ready to integrate. To get started, send me your Unity version, the target platform, reproduction steps, and if possible a video or a minimal project.

My projects:

GitHub (games published on Itch.io (full portfolio (bit.ly/doriann-xavier).

Ideal clients: All types.
