Work on a already existing unity project

I am looking for an experienced Unity Developer to work on an existing Unity project. This project is for personal use, and it has already been completed - I am now looking to add additional functionality and configure the project and build the application out of it. I will need someone with experience in Unity and game development, as the project includes both. I am looking for someone who can create high-quality code with excellent attention to detail. Good communication skills and the ability to finish tasks in a timely fashion are also essential. The additional functionality should be fully tested and should be designed to meet the standards of the original product.
