Hello,
I am an video games programmer-developer with expertise in Unity3D. I have worked on various projects for mobile and web applications for more than 5 years. I believe I have the skills to fullfill the requirements of this project due to my mathematical background and my experience with this game engine.
The attached document is quite descriptive and I am sure it will not need more than a week to implement all tweaks and deliver. During this time you will get demo versions to track progress.
I ensure you I will work on it hard enough to make it look as your client wants.
Please have a look at my profile and portfolio and feel free to ask me for more info.
More of my work is available on request.
Kind regards,
Sotiris Danos
