A company in Utah, USA ordered me to developed the anti-cheat system to protect their products (mobile games), which has been up and run on the Google Playstore. So, I designed all structures and implemented it myself. I was in charge of everything. There was no other developer engaged in the project. It is working well now. There has never been any hacks that broke my anti-cheat system so far. I used C++ (Android NDK), cURL, openSSL for frontend and php for backend. That project has been developed with NDA contracts. So, I couldn't upload the project files to any sites like GitHub, that means I can't provide any Website Link, but if you hire me, I will show it to you. 

I developed this project in order to make Unity developer to easily use all fonts when modeling 3D text mesh. I used C++ as Android NDK in Visual Studio and experted it as Unity plugin (DLL).

I worked on it on my own.

This is a project that helps Unity developers easily build 3D models without knowing tricky knowlwdge about 3D modeling. In order to build a 3D model, you have to understand about several things like vertics, meshes, pivots, etc. But in this project, you can easily build 3D models from 2D images without using any other external tools like 3Ds max, Maya,,,. I was the only developer that designed the structure and implmented it all.
